Introduction & Safety Considerations
Congratulations for choosing the Modular Advanced Remote Starter and Keyless Entry
system. The MARS-22 offers the convenience of locking and unlocking your vehicle’s
doors with the press of a button, and starting your vehicle's engine from the comfort of your
home or office, allowing it to warm up in winter and cool down in summer. The MARS can
also be configured to remotely open your vehicle’s trunk.
It is highly recommended that this system be professionally installed, as the sophistication of the modern automobile and the complexity of this type of product installation is often
beyond the abilities of most do-it-yourselfers.
There are several important safety considerations with using and installing the MARS
keyless entry and remote starter. Among them are:
✓ This unit is for vehicles with an automatic transmission only. Installation in a
vehicle equipped with a manual transmission can result in property damage or
personal injury.
✓ This unit is for fuel injected gasoline or diesel engines.
✓ Children should not be left unattended in, or be allowed to play with the activat-
ing transmitters of any remote starter equipped vehicle.
✓ Do not use the remote starter feature in an enclosed garage or other structure.
The MARS is a very flexible system. It has capabilities, such as sounding the horn, which
may or may not be utilized in your installation. It also has many programmable features
which can affect its operation. While these are explained as thoroughly as possible in this
guide, your Omega dealer or installer is the best source for information about your system.

Warning: The Positive pulse system can be confused with the 5-wire Reversing Polarity system. This
is because both systems show +12 Volt pulses on the “Lock” and “Unlock” wires when the vehicle’s
switch is pressed respectively. It is critical to identify which system is present, since if +12 Volts is pulsed
into a Reversing Polarity system, which rests at ground, a direct short circuit will occur.
3 main differences between a Positive pulse and a Reversing Polarity system:

This harness, which plugs into the White 3-pin port on the control module, is the power
doorlock outputs by which the MARS operates the vehicle’s power doorlock system (the
vehicle must have existing power doorlocks). The doorlock interface needed to allow the
system to operate the doorlocks will depend upon the type of power doorlocking system
the vehicle is equipped with. The following sections describe typical power doorlocking
systems, which are categorized as “3 Wire Negative Pulse”; “3 Wire Positive Pulse”, and “5

3 Wire Negative Pulse Systems
This power doorlock system is simplest of all doorlocking systems. A Negative pulse system
will have only three wires at the doorlock switch.
Examine the wires on the back of the doorlock switch:
1) One wire will show Ground, regardless of the switch's position.
2) One wire will show Ground only when the switch is pushed to "Lock".
3) One wire will show Ground only when the switch is pushed to "Unlock".
The lock & unlock wires coming out of the switch operate the vehicle’s doorlock relays or a
control unit with on-board relays, therefore the lock & unlock wires will read Positive voltage,
up to +12 Volts, when the switch is at rest. The correct connection point is between the
switches and the relays. The Red connector's Green and Blue wires can be connected
directly to the vehicle’s Negative pulse system since only a Negative pulse is required to

Valet Mode
The MARS may be placed into a “valet mode” which prevents the remote start feature
from being activated. Valet Mode should always be used when you do not wish for remote
starting to be operated, such as when you have your vehicle serviced or leave it with
someone else. The Valet Switch, in the Receiver Unit, is used to engage Valet Mode:
• At any time simply press the Valet Switch for 5 seconds; the Status Light within the
Receiver Unit will light steady, to indicate Valet Mode, and stay illuminated continuously
while the system is in Valet Mode.
Once the MARS is in Valet Mode, an attempt to remote start will instead be acknowledged
by 1 long and 3 short parking light flashes, but no starting attempt. If the horn is connected,
it will sound briefly and then chirp 3 times.
• To turn off Valet Mode, simply press the Valet Switch until the Status Light turns off.
Valet Mode only prevents the remote starting operation; the lock, unlock, and trunk release
functions all continue to operate when the MARS is in Valet Mode.

An important part of the MARS system is its Receiver Unit. As its name implies,
the Receiver Unit contains the radio receiver needed for the system to operate
from the hand-held transmitter. The Receiver Unit also contains the Valet Switch
and Status Light; the various operations of which are explained throughout this
guide. The Status Light also briefly flashes the number of transmitters able to
operate the system every time that the ignition key is turned on.
The Receiver Unit is designed for mounting directly on the vehicles’ window glass, which also
gives the system its best operating range. Should
this not be possible or desired, the Receiver Unit
may be mounted in a hidden location, and provisions are made for optional separately-mountable
Valet Switch and Status Light.

Programming Features
The MARS has a total of 14 “programmable features”; most of these are “operational”
features, some are “installation”-related, and one returns all features to the factory setting.
These features can be changed by very easily by placing the MARS into a “Features Programming Mode” and selecting features with the Valet Switch, and then using the
transmitter’s buttons to set the feature as desired. The chart on the next page shows the
Programmable Features, and detailed step-by-step programming instructions follow the
chart.

the vehicle is equipped with a Retained Accessory Power circuit, this output can be used to
“spike” the door pin switch wire, which will turn off the Retained Accessory Power circuit.
To arm a factory alarm after remote start engine run stops, connect the Yellow/Red wire
to the vehicle's factory arm wire. This wire will show Negative polarity when a key is held in
the "lock" position in the door key cylinder. This wire can usually be located in either kick
panel, in the wiring harness from the door, as it is routed between the door key cylinder and
the factory alarm.
To use this wire to turn off Retained Accessory Power, locate a vehicle wire within the
door or doorjamb which shows Negative when the door is open. Should such a wire be
found which is positive, a relay is needed to reverse the Yellow/Red wire’s Negative output
to Positive. The Yellow/Red wire produces a Negative pulse output whenever the system
turns off the engine after it has been remotely started.

How to program the features:
1) Turn the ignition key “On”, then “Off”.
2) Within 7 seconds press the Valet Switch 5 times.
The Status Lights will flash twice, and if the horn is connected, it chirps twice.
The parking lights turn on, and stay on while in programming mode.
3) Select the feature to be changed by pressing the Valet Switch the same number of times
as the feature number (example: feature #3 = 3 presses).
The Status Lights will flash the same number as the Valet Switch presses just
entered. If the horn is connected, it also chirps the same number.
Count the number of flashes or chirps to confirm that the desired feature has been
chosen (if needed, reenter the Valet Switch presses).
4) Once the feature has been confirmed, press the transmitter buttons as follows:
“LOCK” = Feature’s Default 1st setting (
“UNLOCK” = Feature’s optional 2nd setting (
• Most of the programmable features offer more than one optional choice:
“START” = Feature’s 3rd setting (
“TRUNK” = Feature’s 4th setting (
1 Status Light flash & 1 horn chirp
2 Status Light flashes & 2 horn chirps
3 Status Light flashes & 3 horn chirps
4 Status Light flashes & 4 horn chirps
)
)
)
)
Once the Status Lights flash a response, and the horn chirps the response
(if connected), the feature is set.

cess. Consider both methods before selecting one to use, and then connect the
Black/Yellow wire accordingly. Either connection method must be performed at
the completion of the installation, after all other wiring connections are made.
Smart Start sensing is more commonly used, for its ease of installation. The unit as
received has Smart Start selected. Smart Start “reads” the vehicle’s battery voltage level
via the Black/Yellow wire to determine engine running status. To use Smart Start:
1) Connect the Black/Yellow wire to constant “Battery” 12 volts. This may done at the
ignition switch harness, or at the battery itself for better sensitivity.
2) Switch the selector slide switch on the MARS control module to the left toward the
module corner (see page 21 and the markings on the control module).
3) Adjust Smart Start by starting the engine and turning the left adjustment screw on the
control module slowly clockwise until the indicator LED starts flashing. Turn the adjustment until the LED is flashing in a consistent and regular manner.
4) Test the operation by remote starting and checking that the indicator LED shows the
same consistent flashing (good voltage signal learned), and that the starter engagement is long enough for the engine to start, but without grinding. Turn clockwise for
more crank time and counterclockwise for less crank time.
Tach Wire sensing is generally more reliable, and preferable in cases were the engine
normally starts inconsistently, or is hard to start . With this method the Black/Yellow wire
reads the engine speed (tach) information directly from a wire in the vehicle. To use the
Tach Wire method:
1) Connect the Black/Yellow wire to the vehicle's tach wire, which is found in the engine
compartment, although in many 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

this wire through the firewall, using an added or existing grommet, avoiding any hot or
moving parts. If there is an existing hood pin switch for an alarm system, you may use it for
this purpose, but the two systems must be diode-isolated. Instead of using a pin switch to
monitor the hood's open or shut status, an Omega AU-46 Mercury Tilt Switch may used.

Exiting Programming Mode:
Simply allow the MARS to time out of Features Programming Mode by not performing
any programming actions for 15 seconds; or, turn the ignition “On” to exit immediately.
The MARS indicates its exit from Features Programming Mode with 2 short and 1
long Status Lights flashes and the parking lights turning off. If the horn is connected it will have 2 short and 1 long chirps.
About the Programmable Features
The MARS Programmable Features are arranged so that the “operational” features, which
are of user interest, come before the “installation”-related features. The purpose of installation-related features is to adapt the MARS to certain vehicle situations; these are to utilized at the time of the installation only.
• Features #1 through #10 have “daily use” benefits, and may be programmed by the user,
if so desired, to suite their preference or needs.
#
• Features
• Feature #14, “Reset All Features To Default”, quickly and conveniently returns all fea-
tures to their factory settings. This is extremely helpful if there has been a mistake in
programming, or if there is any doubt or confusion of the settings.
11 through #13 should not be programmed by the user!
14
Explanations of the User’s “daily use” Programmable Features:
• Feature #1, “Coded Override”, may be used another programmable feature, “Ignition
Activated Anti-Carjacking”. See “Feature #7”.
• Feature #2 is “Engine Running Time”. When MARS remotely starts the engine, the run
time before automatic shut-off is adjustable. A 10 minute run time is the factory setting,
with options of 20, 30 or 40 minutes. When programming (see page 12) press “UNLOCK”
for 20 minutes; press “START” for 30 minutes; press “TRUNK” for 40 minutes; or press
“LOCK” for 10 minute setting.
• Feature #3, “Doors Lock/Unlock Upon Ignition On/Off”, has the MARS automatically lock
the doors when the ignition key is turned on, and unlock them when the key is turned off.
#
• Feature
4, “Horn Confirmation With Doorlocking”, offers several forms of audible confirmation when the doors are remotely locked and unlocked. Audible confirmations in any
form require the connection of the MARS to the vehicle’s horn, or to an optional electronic
siren. Confirmation with remote doorlocking has the horn chirp once after locking, and
twice after unlocking. Two volume levels are selectable and an “On Demand” operation
whereby the first press of the “LOCK” or “UNLOCK” button is silent, and a second press
will produce the confirmation chirp or chirps.
When programming (see page 12) press “UNLOCK” for the On Demand operation;
press “START” to turn off the confirmation chirps; press “TRUNK” for the Quiet chirp; or
press “LOCK” for louder chirp (the factory “Medium” setting).

again, the horn output must be connected. When the MARS remote starts the
engine it will chirp the horn 3 times; this feature allows the choice of 3 chirp volume
levels (instead of two- “On Demand” chirps can’t be used as the “START” button operation toggles between “start” and “stop”), or completely turning off the starting chirps.
The factory chirp setting is “Medium”; when programming (see page 12) press “UN
LOCK” to turn the starting chirps off; press “START” for the loud chirps; or press “TRUNK”
for the quiet starting chirps. Press “LOCK” for the factory setting “Medium” starting chirps.
• Feature #6 is not used on the MARS-22.
Anti-Carjacking Feature and Coded Override:
• Feature #7, “Ignition Activated Anti-Carjacking” is described here in full detail.
The MARS features Anti-Carjacking protection which only requires programming it to
operate, and connection of the horn output. Adding an optional starter interrupt circuit to
the Anti-Carjacking further enhances recovering the vehicle should it still be taken.
When it is utilized, Anti-Carjacking automatically starts operating every time the ignition
key is turned “On”. When the key is turned on, the user has 53 seconds in which the
Valet Switch must be pressed 1 time to cancel the full engagement of Anti-Carjacking. At
53 seconds, the horn will start a chirping pattern as reminder, and the Valet Switch can
still be pressed. At 60 seconds after the key was turned “On”, Anti-Carjacking fully engages, sounding the horn and flashing the parking lights; pressing the Valet Switch will
no longer cancel the feature. Instead, the ignition key must be turned “Off”, then back
“On”, and then within 5 seconds the Valet Switch must pressed; a few seconds later AntiCarjacking will turn off.
• Once the full Anti-Carjacking occurs, the horn output ceases if the ignition key is turned
“Off”, but resumes whenever it is “On”.
15
Anti-Carjacking can be made even more difficult to defeat with the use of “Coded Over-
16
ride” (Feature #1). Instead of 1 Valet Switch press to turn it off after fully engaging,
multiple presses must be made. The number of presses, 1 through 9, are chosen and
programmed by the user Even if a customized Coded Override is used, only one Valet
Switch press is needed to cancel Anti-Carjacking before it fully engages at 60 seconds; after
that point that the correct custom Coded Override must be entered to turn off Anti-Carjacking.
How to program Coded Override:
• Feature #1 allows the user to custom-program the “Coded Override”. Place the MARS
into Features Programming Mode (page 12) and access Feature #1. After the Status
Light flashes once and the horn chirps once to confirm that Feature #1 is ready for programming, press the transmitter “LOCK” button for each digit of the desired customized
Coded Override, but wait after each single “LOCK” button press for a single Status Light
flash and horn chirp before pressing the button again for the next digit. When all of the
digits have been entered in this fashion, wait for the Status Light and horn to flash and
chirp the complete total number.
Example: for a Coded Override of “3 presses”, programming would be: enter Features
Programming Mode, select “feature 1” (

plug the remaining two connectors into their respective 2-pin ports.
Optional: Should it be desired, an optional separately-mountable Valet Switch and

but the Valet Switch and/or Status Light may be placed as desired.
Wiring Connections - 6 Wire Main Harness

must supply adequate amperage. The most common sources are the battery (+) terminal
or the ignition switch wiring harness. Good reliable connections and use of the included
fuses are a must. Note that some ignition switches have the electrical switch as part of the
mechanical switch; others have the electrical switch lower on the steering column and
connected to the mechanical switch by a linkage. The ignition switch wiring harness is the
best source for these wires, and the Starter, Ignition #1 and Accessory wiring connections.

and the horn chirps twice (if connected) when trunk release is used; if this feature
is turned off, the trunk release operates with 2 Status Light flashes only.
• Feature #10 is “Pulsed or Steady Horn / Siren Output”. This feature’s first function is to set
the MARS’ audible output for use with the vehicle’s existing horn, or with an optional
electronic siren. If MARS is connected to the vehicle’s horn, Feature #10’s second function is providing three different horn pulse patterns when it sounds for the “panic” feature.
When programming (see page 12), the three horn pulse choices are: press “TRUNK” for
the slow horn pulses; “START” for medium pulses; or “LOCK” for default medium horn
pulse setting. To use an optional electronic siren, program steady output by pressing
“UNLOCK” when programming. Do not use the steady output setting for the horncontinuous use will damage it.
17
Explanations of the “installation-related” Programmable Features:
Programmable Features #11 through #13 should only be used by the installer. All of these
features program certain aspects of the MARS to match the vehicle into which it is installed. Do not change any of these features once the MARS is installed and properly
configured.
• Feature #11 is “Starter Cranking Time”. This sets the base starter cranking time for the
Smart Start voltage sensing engine detection method (page 29). When using Smart
Start, a longer starter cranking time may be used for engines which do not start on the
first remote start attempt. Programming choices are: .5 second (“LOCK”, the default
setting); .75 second (“UNLOCK”); 1.25 second (“START”); and 1.5 second (“TRUNK”).
• Feature #12 is “Single or Double Unlock Pulse”. The double unlock pulse is needed
18
in certain vehicles. Programming settings are single unlock pulse (“LOCK”) and
double unlock pulse (“UNLOCK”).
• Feature #13 is “Gasoline or Diesel Engine” When programming, press “LOCK” for the
“Gasoline” setting. Diesel engines have three options: pressing “UNLOCK” selects “Monitor
Glow Plug Wire”, by which the MARS delays engaging the starter until its glow plug input
wire detects the glow plugs turning off; and two preset delay periods before starter engagement: 10 seconds (“START”) and 20 seconds (“TRUNK”).
Resetting all of the Programmable Features:
• Feature #14 returns all Programmable Features to their factory default settings. Enter
programming mode (page 12), select Feature #14, and press the transmitter’s “LOCK”
button. The MARS will acknowledge the “LOCK” input with a single Status Light flash
and horn chirp (if connected), and then immediately exit programming mode with the
normal confirmation of 2 short and 1 long Status Light flashes and horn chirps.
Note: When a Programmable Features Reset is used, any feature which needs to be in
a setting different from the default setting will have to be reprogrammed.
Programming Transmitters
The MARS can be operated by up to four transmitters. Replacement or additional
transmitters must be programmed to operate the MARS. The MARS multi-car operation
capability also requires that transmitters be programmed into the second vehicle (with the
transmitter’s multi-car switch in “B” position). Coding transmitters is a very easy process.
mined 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 MARS control module, which is mounted
upon completion of the installation.
The MARS remote starting unit duplicates the actions that occur within the ignition
switch when you use your key to start the engine. Because of this, most of the main wiring
harness connections will be made at the ignition switch harness. The ignition switch wires
usually are high amperage circuits, which means that high reliability connections must be
made- soldering of all connections is recommended.
Caution!

23
Main Module:
The MARS Main Module should be mounted in a location close to the ignition switch
(where many of the wiring connections are made); typically, hidden behind the driver’s
side dash.
Receiver Module:
An essential part of the MARS is the plug-in window mount Receiver Module, which also
contains the Valet Switch and Status Lights. The unit will not operate unless this Receiver
Module is plugged-in. Select a desired mounting location for the Receiver Module; optimum
performance is obtained by mounting this module high and unobstructed on the vehicle’s
glass, such as the windshield behind the rearview mirror. Make sure the glass surface is
clean and free of dust, grease, or debris. Peel the backing off of the adhesive tape

Installation Instructions
After reading this manual, start the installation by affixing the WARNING
DECAL to a visible area in the engine compartment!
Do not attempt to install this 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 required. 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 routed through the firewall from sharp metal edges and
hot parts of the engine! Always fuse positive wires at their source!
• Have present all of the transmitters which are to operate the MARS. When one
transmitter is programmed, all prior transmitters are erased- program all transmitters.
• If the additional transmitters are for a second car, put the multi-car switch on these
transmitters only in the “B” position.
1) Turn the ignition key “On” (and leave it “on”).
2) Within 7 seconds press the Valet Switch 5 times.
The receiver unity’s Status Lights turn on, and the horn chirps once (if connected).
3) Within 15 seconds press the first transmitter’s “LOCK” and “UNLOCK” buttons together.
The MARS will acknowledge the transmission by momentarily turning off the
Status Lights and chirping the horn 1 time.
4) Within 15 seconds press the next transmitter’s “LOCK” and “UNLOCK” together.
The Status Lights turn off and the horn chirps once.
Repeat this action for each remaining transmitter.
19
Exiting Programming Mode:
Simply allow the MARS to time out of the programming mode, by not transmitting for 15
seconds; or, turn the ignition “Off” to exit immediately.
The MARS indicates its exit from programming mode by turning off the Status
Lights and a series of horn chirps.
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 deter-
Any time that transmitters are programmed to operate the MARS, for 48 hours
afterward every time that the ignition key is turned “on” the horn will briefly chirp
and the Status Light will flash the number of operating transmitters. This is
“Unauthorized Transmitter Alert”, protecting against unauthorized transmitters.
