5 Wire Reversing Polarity Systems
Introduction & Safety Considerations
This power doorlock system differs from the negative and positive pulse systems in that there
is no doorlock control unit or relays. In this type of system, the switches themselves supply
the positive voltage directly to the doorlock actuators, and, more importantly, provide the
return ground path. It is important to note that the lock and unlock wires in this system
rest at chassis ground.
cut, to make the proper connections.
Examine the wires on the back of the switch. (Normally 5 wires will be found)
1) One wire will show +12 Volts, regardless of the switch's position.
2) Two wires will be grounded regardless of the switch's position.
3) One wire will show +12 Volts only when the switch is pushed to "Lock".
4) One wire will show +12 Volts only when the switch is pushed to "Unlock".
- When the lock /unlock wires are found, they must be cut one at a time. If the correct wires
are cut the door locking system should not operate from the primary switch.
- Notice that in the diagram the driver's switch is the primary or “Master” switch (in some
vehicles, the primary switch is on the passenger's side). The half of the cut wires which
come from this primary switch are referred to as the "Switch" side. The half of the cut wires
which go to the secondary switch are referred to as the "Motor" side even though the cut
is made between the switches.
This means that both the lock and unlock wires must be "opened", or
actually

Congratulations on your purchase of the COMFORT START Keyless Entry
and Remote Starter unit. The Comfort Start offers you the convenience of locking and unlocking your vehicle’s doors with the press of a button, and the starting
of 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. The Comfort Start can
also be optionally configured to remotely open your vehicle’s trunk.
It is highly recommended 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.
There are several important safety considerations with using and installing
the Comfort Start 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.

3 Wire Positive Pulse Systems
Locking & Unlocking the Doors
This doorlock system is similar to the 3 wire negative pulse system except the doorlock
switches send +12 Volt pulses to operate the doorlock relays/control unit.
Examine the wires on the back of the doorlock switch:
1) One wire will show +12 Volts, regardless of the switch's position.
2) One wire will show +12 Volts only when the switch is pushed to "lock".
3) One wire will show +12 Volts only when the switch is pushed to "unlock".
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:
1) In a Reversing system the Lock/Unlock wires

2) The doorlock switch in a Reversing system will have 5 wires, while a Positive pulse
system the switch will have 3 wires.

This harness, which plugs into the White 3-pin port on the control module, is the power
doorlock outputs which allow the Comfort Start system to operate the vehicle’s existing
power doorlock system. The vehicle must have existing power doorlocks; or, if it does
not, power doorlocks may be added to the vehicle in the form of installing an Omega
actuator to each of the doors, along with a doorlock interface. 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 Wire Reversing Polarity”
systems
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
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
only when the switch is pushed to "Lock".
34
Upon entering the vehicle place the ignition key in the switch and turn it to the
"On" position. Do not turn the key to the "Start" position.
Deactivation
- After the preset programmable time the Comfort Start will turn the engine off.
- To stop the engine by remote control, simply press the upper button again.
- Stepping on the brake pedal will turn the engine off.
- Opening the hood will turn the engine off. If the hood is open when an activation
attempt is made, the Comfort Start will only flash the parking lights once, chirp
the horn 3 times, but will not start the engine.
- Pressing the Valet Switch will also stop the engine.
Valet Mode
The Comfort Start 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 leave your
vehicle with someone else. The Valet Switch, within the clear Receiver Unit, is
used to engage the 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.
7
Page 8
Once the Comfort Start 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 and then chirp 3 times.
- To turn off Valet Mode, simply press the Valet Switch.
The Receiver Unit
An important part of the Comfort Start 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 operations of which are explained throughout this guide.
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.

change in voltage when the dimmer is operated. Some vehicles have a parking-light
relay which is triggered by a Negative signal from the headlight switch. In these vehicles,
the White wire must be connected after the relay, usually at the Fuse/Junction Block. Do
NOT connect the White wire directly to the vehicle’s headlights. An external relay is
required. Vehicles having a split

Programmable Features
The Comfort Start has 11 programmable features, some of which are “operations” features and others are installation-related. These features can be changed
by using the transmitter when the unit is in Features Programming Mode. To
access Features Programming Mode:
1) Turn the ignition key “On”, then “Off”.
2) Within 7 seconds press the Valet Switch 5 times. The parking lights will flash
twice, the Status Light illuminates and the horn chirps twice.
3) Select the feature to be changed by pressing the Valet Switch the same number of times as the feature number; the unit’s response is an equal number of
horn chirps.
4)Once the feature has been confirmed by the horn chirps, press either the
transmitter’s left “LOCK” button (1 chirp & parking light flash) or the right
“UNLOCK” button (2 chirps & parking light flashes) for the “option” setting.
- Some of the features offer multiple choices, so further transmitter buttons may
be pressed. See the following descriptions of each feature.
5)Select another feature by repeating step “3)” and “4)”, or allow the unit to exit
Features Programming Mode by turning the ignition “On” or by simply not performing any programming actions- after 15 seconds the system chirps once
and flashes then turns off the Status Light to indicate its exit from Features
Programming Mode.

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.
- “Engine Running Time” (feature #4) is adjustable so that remote starting the
engine will allow it to run for 10, 20, 30 or 40 minutes before it automatically
stops. When programming as described on page 11, at step “4)” set the time as
follows: press “LOCK” for 10 minutes; press “UNLOCK” for 20 minutes; press
“START” for 30 minutes; or press “TRUNK” for 40 minutes.

devices such as an existing keyless entry or alarm system to activate the remote start
operation. If the Pink/Black wire receives a Negative pulse, the Comfort Start unit will
start the vehicle's engine, provided that all safety circuits are in the proper status. After
the engine has been started by remote control, another Negative pulse on the Pink wire
will turn the unit off, stopping the engine.
The Pink/Black wire can be connected to an available auxiliary output of an existing
Remote Security System, and the unit's remote control may also be used to activate the
remote start operation.
Should it be desired to activate the unit’s remote start operation from an existing
keyless entry system, programmable feature #6 will configure the Pink/Black wire to
activate the remote start feature only if it receives two Negative pulses within 10 seconds. This allows configuring the unit to remote start when the OEM transmitter’s “LOCK”
button is pressed twice. In most cases the existing keyless entry system will have Negative switching door lock circuits to which the Pink/Black wire may be connected directly.
In the other cases, an optional relay is needed to reverse Positive polarity to Negative.

- “Unlock Doors With Trunk Release” (feature #7) can be changed, so that operating trunk release will not also automatically unlock the doors.
- “Doors Lock/Unlock Upon Ignition On/Off” (feature #8), being factory-set “on”,
automatically locks the doors when the ignition key is turned on, and unlocks
them when the key is turned off. If desired, this feature can be turned “off”.
- “Horn Confirmation With Doorlocking” (feature #9) actually has three options.
The factory setting (press “LOCK” when programming) has automatic confirmation chips with doorlocking operation. One option (press “UNLOCK” when
programming) has the chirp when doorlocking “upon demand” via pressing the
transmitter again a second time. The second option (press “START “ when
programing) completely turns off the chirp confirmation.
- “Horn Confirmation With Engine Start” (feature #10) can be changed, so that
the 3 horn chirps upon remote starting are turned off.

Programming Transmitters
The Comfort Start includes with two pre-programmed transmitters, and up to four
transmitters total may be programmed to operate it. Transmitters, other than the
originals, must be programmed to operate the Comfort Start. When an additional
or replacement transmitter is added to operate the unit, all of the transmitters must
be programmed as any existing transmitter code is erased from the system.
1) Turn the ignition switch “On” (and leave it “on”).
2) Within 7 seconds press the Valet Switch 5 times. The parking lights and Status
Light will illuminate, and the horn chirps once to indicate that the unit is ready to
receive the first transmitter code.
3) Press the transmitter’s upper “START” button. The system will acknowledge
the transmission by momentarily turning off the Status Light.
4)Repeat the previous step for each remaining transmitter.
The system will automatically exit the transmitter programming mode by turning
the ignition key “off”, or 15 seconds after the last transmission.
Any time that transmitters are programmed to operate the Comfort Start, 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.

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

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 read 1 to 6 volts AC with the engine idling, and will
increase with engine speed.
Learning the Tach Wire Sensing must be performed after all wiring connections are
made, and the Comfort Start unit has been programmed for Tach Wire Sensing operation
(the unit must be programmed- see pages 11-13). To perform the learning:
1- Turn the key on and off, then step the brake pedal 5 times.
2- Within 5 seconds, start the engine with key. The unit will chirp the horn once, if
connected, to indicate tach learning mode.
3- The Status Light will light to indicate that the tach signal is learned.
4- The unit will exit tach learning mode automatically 7 seconds later, or by stepping on
the brake pedal, upon which the unit will chirp the horn once and the Status Light will
go out.

Installation Instructions
IMPORTANT!
After reading this manual, start the installation by affixing the
WARNING DECAL to a 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 Comfort Start control module, which is mounted
upon completion of the installation.
The Comfort Start 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!

Installation Cautions and Warnings
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!

Instead of using a pin switch to monitor the hood's open or shut status, an Omega

wire. The Comfort Start unit utilizes two different methods of monitoring the vehicle during the remote starting process. Consider both methods before selecting one to use:
Smart Start is more commonly used, for its ease of installation and especially for applications such as diesel engine in which the vehicle has no true tach signal available or an
unsatisfactory tach signal. The unit as received has Smart Start selected, and when it is
used the Black/Yellow wire is not connected to anything. Smart Start “reads” the vehicle’s
voltage level to determine engine running status.
An adjustment control for Smart Tach is on the side of the unit’s case. Complete all
wiring connections; then start the engine by pressing the transmitter’s START button. If
the engine can’t be started, turn the adjustment clockwise. If the engine is over cranking,
turn the adjustment counter-clockwise.
Tach Wire Sensing is preferable in cases were the engine normally starts inconsistently, or is hard to start . To use this method, Tach Wire must be programmed to operate
(see pages 11-13), the Black/Yellow wire must be connected, and then the Tach Wire
signal must be learned by the Comfort Start unit.
With this method the Black/Yellow wire reads the engine speed (tach) information.

Connect the Red/Black wire to the brake switch wire which shows +12 Volts when the
brake pedal is pressed. The brake switch is typically located above the brake pedal, and
usually mounted to the brake pedal support bracket. Make this connection securely for
long-term reliability, and thoroughly test the operation of this circuit.

and the Blue wire must be connected. This prevents operation of the unit if the hood
is open. Carefully install the included pin switch so that it is open (pin down) when the
hood is shut and closed (pin up) when the hood is open. Connect the Blue wire to the pin
switch and carefully route 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.

Main Module:
The Comfort Start 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 Comfort Start is the plug-in window mount Receiver Module, which
also contains the Valet Switch and Status Light. 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 and affix the Receiver Module. Carefully route the module’s 5-wire ribbon
cable to the Comfort Start control module; plug the cable into the Black 3-pin port on the
rear of the module, and plug the remaining two connectors into their respective 2-pin ports
on the front of the module.
Optional: Should it be desired, an optional separately-mountable Valet Switch and
Status Light are available. The Receiver Module must still be used for its receiver section,
but the Valet Switch and/or Status Light may be placed as desired.
