Congratulations on your purchase of the RS-4LX Deluxe Modular Remote Car Starter.
The RS-4LX will allow you to start your vehicle's engine from the comfort of your home
or office, allowing your vehicle to warm up in winter and cool down in summer. When
you leave your vehicle, simply set the climate controls for what you desire to be operating
upon remote start - heater, defroster or air conditioning.
Omega Research and Development, Inc. has been a leader in vehicle security and vehicle convenience products since 1970. Your RS-4LX is quality engineered, microprocessor controlled and manufactured in the U.S.A. It is an extremely sophisticated system
with multiple built-in safety and security features. We highly recommend that this system
be professionally installed, as the complexity of the modern automobile and the nature of
circuits to be accessed is often beyond the abilities of most do-it-yourselfers.
The RS-4LX is an "add on" unit designed to be used in conjunction with another remote control unit such as a remote vehicle security system, a keyless entry device or a
remote receiver unit. Because the host activating unit will vary from application to application, the proper button or buttons to press to activate the remote starter can only be
determined by the installer.
Please take time to review this manual, which is divided into two parts. The first
section will explain the operation of your RS-4LX Deluxe Remote Car Starter, and the
second section provides instructions for the installer.

Other OEM Anti-Theft Systems: There are other OEM antitheft systems which will
require attention when installing a remote starter. In General Motors vehicles, an advanced form of VATS known as PASSLOCK will require an optional bypass. In certain
Ford vehicles, a transponder-based Passive Anti-Theft System (PATS) will also require an
optional bypass. Both of these bypasses are available from Omega, and complete instructions are included with each.
The RS-4LX And REC-2
ATV
Modular Remote Keyless Entry/Starting System:
The RS-4LX can be used with the REC-2
ATV
keyless entry receiver in an easy-to install
modular fashion. The RS-4LX control module has a Black 5-pin port which supplies the
necessary circuits for the REC-2
ATV
's operation, and also the return circuit which activates
the RS-4LX. An optional wiring harness (H-RS5) is all that is required for the direct
connection of the two control modules.
Please note that the operation of the "Trunk"
and "3rd Channel" differ- "the "trunk" button
must be pressed for 2 seconds to obtain the
output while pressing the "Option" button
produces an instant output. Both of these
wires are connected on the H-RS5
wiring harness; this allows the installer
to choose the timing for remote starting.

There are several safety considerations with using and installing the RS-4LX Remote
Car Starter. Among them are:
- This unit is for Automatic Transmission vehicles only. Attempting installation in a
manual transmission equipped vehicle can result in property damage or personal injury.
- This unit is for fuel injected gasoline and diesel engines only.
- Children should not be left unattended in, or be allowed to play with the activating transmitters of a remote starter equipped vehicle.
- All installation safety features should be utilized and safety warnings heeded.
Activation: Your RS-4LX Remote Car Starter is activated by remote control. This is
typically done from a small radio transmitter, usually attached to your key ring. As stated
previously, the RS-4LX is an "add on" unit designed to be used in conjunction with another remote control unit such as a remote vehicle security system, keyless entry device or
remote receiver unit. The exact activation method for your vehicle may vary. The normal
activation involves pressing and releasing either a single or multiple button(s) on the transmitter. Please note that other reactions may occur, depending on the host receiver unit.
For example, if a security system's auxiliary output is being utilized, it may also disarm or
it may chirp its siren. As noted earlier, the installer can determine the exact remote start
activation procedure, and also inform you of the total reactions of your particular system.
1) Using a Digital Multimeter (DMM) or a Volt-Ohm Meter (VOM) measure the resistor
in the ignition key. This is the small black pellet in the shank of the key. If the meter is not
auto-ranging, set it for the "100kW " scale. When measuring the key, do not touch the
metal parts of the meter probes or erroneous readings can occur.
2) Select the proper value of the 15 included resistors. Use the meter or the following
chart to make the proper selection:
Key Number Value 2% Resistor Band Colors
1 392W Orange, White, Red, Black
2 523 W Green, Red, Orange, Black
3 681 W Blue, Gray, Brown, Black

When the exterior lights turn on (if connected), confirming the RS-4LX Remote Car
Starter's activation, the following events will also occur:
1) The vehicle's Ignition circuit will also turn on when the exterior lights turn on.
2) Two seconds after activation, the parking lights will turn off, and the Starter will
engage. The Ignition circuit will remain on throughout this process.
3) The engine will start to run, which will be detected by the RS-4LX, and the
Starter will automatically be disengaged.
4) Seven seconds later, the exterior lights (if connected) will turn back on, and stay
on for the duration of the period that the engine is running by control of the
RS-4LX.
5) If the engine stalls, the unit will make two attempts to restart it.
6) After ten (or fifteen) minutes the RS-4LX will automatically turn the engine off.
Safety Features And Deactivation: The RS-4LX includes multiple built-in safety
features. The unit will not engage if the gear shift selector is in a forward or reverse gear
position. The unit will not engage if the hood is opened. If the engine is running by remote
control, either of these actions will cause the engine to stop running.
The RS-4LX may be deactivated by several methods. To stop the engine by remote
control, you may simply press again the transmitter button(s) used to activate the unit. For
normal operation, once you have entered the vehicle, stepping on the brake pedal will
deactivate the unit. If you first used your vehicle's key to turn the ignition switch on (do
not turn to the Start position), the engine will remain running after the RS-4LX is deactivated. The Override Switch may also be used to deactivate the unit while it is operating, in
addition to preventing activation.
General Motors VATS: Commonly encountered in certain General Motors vehicles
is the Vehicle Anti-Theft System (VATS). The VATS first appeared in the 1986 Corvette
and has become very popular because of its ease of use and effectiveness.
The VATS consists of a pellet resistor in the shank of the ignition key, which is read
by a decoder in the VATS control module. When the key is inserted into the ignition
switch, if the decoder reads the correct resistance value, it will allow the starter to engage.
In later model systems, the fuel pump is also controlled; in the latest versions the engine
control system will not allow the engine to stay running. When installing a remote starter
in a VATS equipped vehicle, an optional AU-VAT bypass kit is required:

Functions Of The Override Switch And Other Options: Your RS-4LX Remote Car
Starter includes an Override Switch which performs several functions. Some of these
functions allow your installer to perform various operations necessary during the installation, and are discussed further in the Installation Instructions section. The uses of the
Override Switch for everyday operations are:
1) Valet Override: The position of the Override allows or prevents the RS-4LX
from being activated. This feature is used when you do not wish the unit to be
operated, such as when you leave it with a Valet Parking attendant or if you loan
your car to another person. To engage the Valet Override mode, simply turn the
Override Switch OFF. When leaving your vehicle with persons such as other
users, garage or valet parking attendants, it is recommended to always turn the
Override Switch OFF to prevent unintentional or unauthorized or unintentional
use of the RS-4LX Remote Car Starter.
2) Deactivation: The Override Switch may be used to turn off the engine if it is
running under remote control. To use the Override/Reactivate switch to turn off
an engine running on remote control, turn the switch OFF.
3) Pit-StopTM Option: This feature allows you to turn the ignition switch off, re-
move your keys, leave the vehicle and lock your doors while the RS-4LX keeps
the engine running. To use this feature, have your foot off of the brake pedal and

flip the Override Switch OFF, ON, OFF, ON just before you remove the key. The
vehicle's engine will run for ten minutes (15 minutes optional), or until you press
the transmitter button or step on the brake pedal. This feature is handy if you want
to run into a store for a minute, but wish to leave the engine running while taking
your keys with you.
4) Optional Pre-Activation Enable: This option can be programmed by the installer.
Pre-Activation Enable requires that the Override Switch be switched OFF, then
ON every time you remove the key and exit the vehicle if you plan on using the
Remote Car Starter later. This option ensures that the Remote Car Starter cannot
be engaged without predetermination of intended use and is a very desirable
option for the safety-conscience person.
5) ClimaSenseTM Option: This feature will automatically start your car's engine, if
desired, under the following conditions: should the temperature drop below 0OF
(-18O C) or rise above 140OF (78OC), or if the battery voltage drops below 11 volts.
The engine will run for the normal 10 (or 15) minute period and turn off. To
engage the ClimaSenseTM option, turn off the engine and then within 5 seconds
press the brake pedal twice. The exterior lights will flash (or the accessories will
turn on) once to confirm that the ClimaSenseTM has been activated. The
ClimaSenseTM will automatically start the engine no more than once every 3 hours
and for a maximum of 5 separate times. Pressing the brake at any time after the
ClimaSenseTM has activated will disable this feature.

Also remember that certain vehicles require considerable amounts of current for cli-
mate control circuits. In these cases, additional relays may be required.
Another unusual circumstance occurs in some imports. When the ignition switch is in
the "Off" position, the start and ignition terminals overlap, which results in the ignition
circuit powering the starter when the remote starter is engaged. Affected vehicles are the
1993 & up Nissan Altima, the 1990 & up Toyota Tercel and the 1994 & up Toyota Camry.
In these cases a relay must be added to interrupt the ignition wire so that voltage does not
backfeed the starter circuit through the ignition switch. Interrupt the Black/Red wire in the
Tercel, the Black/Pink wire in the Altima and the Black/Orange wire in the Camry.
Multiple Ignition Or Starter Circuits: When more than two Ignition circuits or
more than one Starter circuit is encountered, the optional dual relay socket and relays may
be used. A new feature of the RS-4LX is the Red 3-pin port found on the side of the
control module which contains activation circuits and a (+) 12 Volt supply for the optional
relay's coils.
The dual socket's Red connector plugs directly into the matching Red port found on
the RS-4LX control module. Its Red wire connects to a source of constant (+) Volts; if this
source is not fused a fuse and holder must be added. The remaining Green wire is an
additional Starter circuit and the Blue wire is an additional Ignition circuit.
In a situation where two additional Ignition circuits are desired but an additional Starter
circuit is not, the small Green wire may cut and spliced to the small Blue wire; the large
Blue and Green wires are now both Ignition circuits.
flip the Override Switch OFF, ON, OFF, ON just before you remove the key. The
vehicle's engine will run for ten minutes (15 minutes optional), or until you press
the transmitter button or step on the brake pedal. This feature is handy if you want
to run into a store for a minute, but wish to leave the engine running while taking
your keys with you.
4) Optional Pre-Activation Enable: This option can be programmed by the installer.
Pre-Activation Enable requires that the Override Switch be switched OFF, then
ON every time you remove the key and exit the vehicle if you plan on using the
Remote Car Starter later. This option ensures that the Remote Car Starter cannot
be engaged without predetermination of intended use and is a very desirable
option for the safety-conscience person.
5) ClimaSenseTM Option: This feature will automatically start your car's engine, if
desired, under the following conditions: should the temperature drop below 0OF
(-18O C) or rise above 140OF (78OC), or if the battery voltage drops below 11 volts.
The engine will run for the normal 10 (or 15) minute period and turn off. To
engage the ClimaSenseTM option, turn off the engine and then within 5 seconds
press the brake pedal twice. The exterior lights will flash (or the accessories will
turn on) once to confirm that the ClimaSenseTM has been activated. The
ClimaSenseTM will automatically start the engine no more than once every 3 hours
and for a maximum of 5 separate times. Pressing the brake at any time after the
ClimaSenseTM has activated will disable this feature.

Also remember that certain vehicles require considerable amounts of current for climate control circuits. In these cases, additional relays may be required.

!! WARNINGS !!
Do not attempt to install the RS-4LX Remote Car Starter into a manual transmission vehicle! Doing so could cause serious property damage, personal injury, and will void all warranties!
Be aware of, and avoid, any airbag circuitry! Due to the fact that an installer
will not be in a normal, upright seated position, severe injury may occur in an
accidental airbag deployment!
The use of a Digital Multimeter (DMM) or Volt-Ohm Meter (VOM) instead of
a standard testlight is recommended. This can greatly reduce the risk of an
accidental airbag deployment or on-board computer damage.
Battery gases are explosive! Avoid sparks and do not smoke while working
near the vehicle's battery!
Always protect wires ran through the firewall from sharp metal edges and hot
parts of the engine! Always fuse positive wires at the battery or power source!

IMPORTANT! After reading this manual, start the installation by affixing
the WARNING DECAL to a readily visible area in the engine compartment!
Installation Considerations: This entire booklet should be read before starting the
installation. An understanding of which control module wires are to be used and their
functions is essential. Installations will vary from car to car , as some control module wires
are required, while others are optional. Before starting the installation, it should be determined which control module wires will be used. Most installers will list these wires, then
"map out" the installation by locating and noting the target wires in the vehicle. This will
also determine the best location for the RS-4LX control module, which is mounted upon
completion of the installation.
The RS-4LX duplicates, with on-board control circuitry and relays, the actions that
occur within the ignition switch when you use your car's key to start the engine. Because
of this, most of the main wiring harness connections will be made at the ignition switch
harness. This will be located around the steering column area. Caution! Avoid the Airbag
circuit! Especially avoid any harness or wires encased in Yellow or Red tubing or sleeves.
Do not use a standard test light, as it can deploy an airbag or damage on-board computers
and sensors if the wrong circuits are probed.
The ignition switch wires usually are high amperage circuits, which means that high
reliability connections must be made! We recommend proper soldering of all connections. Some installers connect a battery charger to the vehicle's battery during the installation to prevent battery drain. While this is a good practice, the battery charger must be
removed before attempting to use the RS-4LX to start the engine.

Make the following wiring connections and procedures in the following
order. Remember, proper, high reliability connections must be made!
Black Wire: Connection Required
Connect the Black wire to a very good, clean chassis ground. Recommended areas
are to an existing machine thread bolt, either in the driver's kick panel area or a major
structural member behind the dash. Small dash braces are not adequate, and the area must
be clean, bright metal. Use the largest existing machine threaded bolt available. Using a
sheet metal screw or grounding to sheet metal is inadequate.
Red Wire: Connection Required
Connect this wire to Positive battery voltage. The most common source is the battery's
Positive terminal. Carefully route the long Red wire through the firewall, using an added
or existing grommet. Avoid any hot or moving parts. The small bare terminal snaps into
the fuse holder. Connect the ring terminal attached to the fuse holder to the battery's
Positive terminal. Insert the Green 30 amp fuse into the fuse holder. Note: The RS-4LX
will respond to being powered-up by flashing the Diagnostic LED Light once.

be connected at the ignition switch wiring harness, but the fuse holder and 30 amp fuse
must also be used.
The use of the 30 amp fuse and the fuse holder is required! Failure to
properly install the fuse holder and the 30 amp fuse will void all warranties.

If a security system is present which utilizes a starter interrupt circuit, the Green wire
connection must be on the Starter side of the interrupt, not the Ignition Switch side.
Yellow Wire: Connection Required
Connect this wire to the vehicle's Ignition #2 wire. This circuit, known as Secondary
Ignition, varies in its function. In some vehicles, it is required to allow the engine to run,
while in others, it supplies the Heat, Ventilation and Air Conditioning (HVAC) system.
This output's operation is identical to the Blue wire Ignition #1's operation. The connection point for this wire is also found in the ignition switch wiring harness.
One of the primary reasons for adding a Remote Car Starter is to allow the vehicle to
warm up in winter or cool down in summer. The Heating, Ventilation and Air Conditioning (HVAC) circuit varies from car to car in its operation. Usually, the Yellow
Ignition #2 is connected to this circuit. Some vehicles, however, will require the HVAC
circuit to be connected to the White Accessory wire. Once identified, test the wire powering the HVAC circuit; if it has Positive 12 Volts while starting, use the Yellow wire. If
Positive 12 Volts is not present while starting, use the White wire.
The Yellow wire must be connected; if there is no use for this wire, connect to the
Ignition #1 circuit along with the Blue wire. If the White wire is needed to power the

White Wire: Connection If Desired
This wire is used to turn on the vehicle's exterior lights if not needed for the HVAC
system. It can be connected to either the parking lights or the headlights, but not both
unless a pair of relays are used. The parking lights will allow for a 360O field of view for
a visual confirmation that RS-4LX has been activated. If connecting to the headlights,
connect to the low beams. In addition to visual confirmation of activation, the headlights
can be used to light the way to the car or house. The best place to access these wires is at
the light switch, although in a small number of vehicles, notably Toyotas, these circuits are
Negative Ground at the light switch. In Toyotas, the White wire may be connected directly to the Positive parking lights circuit by finding a Green wire in the driver's kick
panel or at the fuse marked "Tail".
The parking light wire will show Positive 12 Volts when the light switch is in the
"Parking" and "Headlight" positions. When such a wire is located, be sure to operate the
dash light dimmer control. If your meter shows a change in voltage, the wire being tested
is the dimmer circuit, which is the incorrect wire. Connecting the White wire to a dimmer
circuit can damage the dimmer control.
The headlight wire will show Positive 12 Volts when the light switch is in the "Headlight" position only. If the High/Low Beam switch is part of the light switch, there will be
separate high beam and low beam wires.
In some cars the Accessory wire at the ignition switch may need powering; examples
are to allow the HVAC system to operate or to keep dash warning lights off . If this need
is encountered, the White wire may be used for this purpose instead of being applied to the

After calculating the required current draw, always fuse the added relays at their source.
Further understanding of ignition switch operation is to view it from a schematic
level. The following schematic is of a basic ignition switch, such as those found in many
older vehicles. Many early Asian imports had as little as four wires total at the ignition
switch, although there were variations on ignition switch positions. Note that the operating parts of the Ignition Switch consists of two separate sets of electrical contacts (or
Accessory: Power is supplied only to Accessory circuits, which usually are the radio and wipers. These circuits are also
powered in the "Run" position.
Start: This position supplies
power to the Starter circuit. In this
position the Ignition circuit is also
powered.
Lock: No circuits are powered and
the steering wheel is locked.
* An exception is power supply to the transmission control module in some late model G.M. vehicles.
Understanding Ignition Switch Operation: Since the RS-4LX duplicates the ac-
tions that occur within the ignition switch, understanding how an ignition switch operates
is helpful in determining the proper installation parameters. This is especially true of
newer vehicles, which are utilizing more and more multiple Ignition and Accessory circuits. The following are the ignition key positions of a typical ignition switch:
Run: Supplies power to the Ignition,
HVAC and Accessory circuits. All circuits necessary for normal operation.
Off: Typically, no circuits are powered.*

The headlight wire will show Positive 12 Volts when the light switch is in the "Headlight" position only. If the High/Low Beam switch is part of the light switch, there will be
separate high beam and low beam wires.
In some cars the Accessory wire at the ignition switch may need powering; examples
are to allow the HVAC system to operate or to keep dash warning lights off . If this need
is encountered, the White wire may be used for this purpose instead of being applied to the

After calculating the required current draw, always fuse the added relays at their source.
Further understanding of ignition switch operation is to view it from a schematic
level. The following schematic is of a basic ignition switch, such as those found in many
older vehicles. Many early Asian imports had as little as four wires total at the ignition
switch, although there were variations on ignition switch positions. Note that the operating parts of the Ignition Switch consists of two separate sets of electrical contacts (or
Accessory: Power is supplied only to Accessory circuits, which usually are the radio and wipers. These circuits are also
powered in the "Run" position.
Start: This position supplies
power to the Starter circuit. In this
position the Ignition circuit is also
powered.
Lock: No circuits are powered and
the steering wheel is locked.
* An exception is power supply to the transmission control module in some late model G.M. vehicles.
Understanding Ignition Switch Operation: Since the RS-4LX duplicates the ac-
tions that occur within the ignition switch, understanding how an ignition switch operates
is helpful in determining the proper installation parameters. This is especially true of
newer vehicles, which are utilizing more and more multiple Ignition and Accessory circuits. The following are the ignition key positions of a typical ignition switch:
Run: Supplies power to the Ignition,
HVAC and Accessory circuits. All circuits necessary for normal operation.
Off: Typically, no circuits are powered.*

Multiple Accessory Circuits: As mentioned earlier, the RS-4LX, with on-board con-
trol circuitry and relays, duplicates the actions that occur within the ignition switch when
the car's key is used to start the engine. The RS-4LX as is can power two Ignition circuits
and one Accessory circuit, which is sufficient for most remote start installations. However, some vehicles will require that further circuits be powered to allow the engine to run
the Heating, Ventilation and Air Conditioning (HVAC) system to operate or other subsystems to operate properly. The optional double relay socket and 30 Amp Single Pole
Double Throw (SPDT) automotive relays are needed for additional circuits when multiple

then monitors for a voltage increase which occurs when the alternator has output. This
circuit automatically compensates for voltage, temperature and the amount of time since
the vehicle was last operated. The Smart TachTM feature is preset at the factory, and if
utilized, the Orange wire is not used. Note that when using this method, if the engine is
hard to start, Programmable Feature #3 will allow 50% more starter time.
Tachometer Sensing:
This method requires connection of the Orange wire. If the vehicle is generally hard to
start (requiring the starter to be engaged for more than 1 second) this method will produce
more consistent remote starting. With this method the Orange wire reads the engine speed
(tach) information from a wire in the vehicle. The Orange wire connects to the vehicle's
tach wire, which is found in the engine compartment, although in some cases it may also
be located inside the vehicle. To use a multimeter to verify the correct tach wire, set it for
AC Volts scale. The correct wire will read 1 to 6 volts AC with the engine idling, and will
increase with engine speed. Once the Orange wire connection has been made, this procedure must be followed:
1) Turn the Override Switch OFF. Wait 5 seconds for the Diagnostic LED Light to
stop flashing. Press the Left Control Button once and the light will respond with
one flash. Now push the Right Control Button once. The light will flash once
again (If the light flashed twice, press the Right Control Button again until only

Additional Auxiliary Connections Which May Be Required
The RS-4LX may typically be installed with and activated by a Remote Vehicle Secu-
rity System or the vehicle may have an existing factory security system. The remaining
Auxiliary Harness connections may be necessary to allow compatibility between the security system and the Remote Car Starter.
Pair Of Blue (18 Ga.) Wires:
The Blue wires are used if remotely starting the vehicle causes a false alarm because
the shock sensor is triggered. The Blue wires consist of a loop which is routed through a
relay inside the RS-4LX. This loop is opened whenever the Remote Car Starter is activated, which allows a security system with a shock or motion sensor to remain armed.
White (18 Ga.) Wire: Connection Optional
The White wire is an Accessory Pulse circuit, which upon the unit's activation, will
have a Negative pulse just as the Main Harness White wire has output and then a 3 second
output pulse after the engine starts. The function of this wire is to allow defroster operation in some vehicles and to control the Retained Accessory Power (RAP) system in some
General Motors vehicles. If this circuit is needed, the White wire must be connected to an
optional AU-SOCKET-5 and a standard Single Pole Double Throw automotive relay.
Page - 22
Yellow (18 Ga.) Wire:
The RS-4LX Yellow wire's operation has changed from the previous model! The
Yellow wire now has (+) 12 Volts output.
The Yellow wire is a (+) 12V output which will directly supply the host remote keyless
entry or security system's ignition input circuit. This circuit has voltage whenever the
ignition switch is on, but not when the RS-4LX energizes the ignition circuit. Connection
is needed on keyless entry systems and security systems which cannot be operated if the
ignition switch is on. If this circuit is not used on such a system, the alarm's transmitter,
after remote start activation, would not disarm the alarm or turn off the RS-4LX. Connect
the RS-4LX Yellow directly to the host unit's ignition input wire.
Brown Wire:
The Brown wire is designed to disarm a factory installed security system. Some factory systems must be disarmed to allow remote starting. In most cases, the Brown wire
may be connected directly to the factory alarm disarm wire. The correct vehicle wire will
show Negative ground when the key is used to unlock the doors or trunk. This wire is
usually found in the kick panel area in the wiring harness from the door into the cabin.
