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.

Wiring Connections - 12 Wire Harness
The Hood Safety Switch must be installed
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 grom-
met, 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.
20-Gauge Blue Wire:
( - ) Hood Input
Connection Required-
18-Gauge Black Wire:
System Ground
Connection Required.
Connect the Black wire to a very good, clean chas-
sis ground. A recommended connection is to an existing machine-thread bolt, either in
the driver's kick panel, steering column area or a major structural member behind the
dash. Small dash braces are not adequate, and the area must be clean, bright metal.
20-Gauge Red/Black Wire:
( + ) Brake Input
Connection Required-
The Red/Black wire must be connected. It is part
a critical safety feature which disables the unit whenever the brake pedal is pressed.
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.
