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

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.

Basic Transmitter Functions
The Comfort Start includes with two 5-button remote transmitters.* Please familiarize yourself with the control buttons, as shown here, and operations of the
transmitters and Comfort Start system which are explained in the following pages.

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