VIOLET w/WHITE:
Tach Sensor Input
This wire will continually monitor the engine tach rate while the unit is under power of the Remote Start system.
This wire will be routed to the vehicle ECM tach input or through the firewall into the engine compartment and
connect to the negative side of the ignition coil. This Remote Start system learns the tach rate of the vehicle and
in most cases will operate properly from one multi coil pack regardless of the number of cylinders. If the vehicle
has a single coil system for each cylinder, it may be necessary to connect this wire to more than one coil for
proper tach reference. shown in the feature programming chart.
WIRING THE 4 PIN HARNESS:
This harness provides low current outputs to control various functions in the vehicle during different stages of the
Remote Start system's operation. Understanding these outputs and the time in which they occur will allow you to
determine if they are needed for the particular vehicle you are working on, as well as how to use them.
Green w/Black:
Pulsed Ground Output Before Start
The Green w/Black wire will provide a 1 second 300mA pulsed ground output 1.5 second before the remote start
system activates as well as when the transmitter is used to unlock/disarm the system. Typical use for this output
would be to disarm a factory theft deterrent system to prevent false triggering of the factory alarm when the
Remote Start system engages.
Blue:
Pulsed Ground Output After Start
The Blue wire will provide a 1 second 300ma pulsed ground output after the vehicle is started under control of
the Remote Start system. Typically this wire will be used to re-lock the vehicle doors if the doors unlock
automatically when the factory anti-theft system is disarmed.
Black w/ Red:
Pulsed Ground Output After Shutdown
The Black w/ Red wire will provide a 1 second 300 mA pulsed ground output after the Remote Start system shuts
down. This output will occur regardless of whether the circuit times out or is manually terminated. Typically this
output will be used to re-lock the vehicle doors if the doors unlock automatically when the ignition circuit
transitions to OFF.
Black w/ Yellow:
Ground Output During Start (Crank)
The Black w/ Yellow wire will provide a 300mA ground output while the starter output of the Remote Start system
is active. This output can be used to activate the Bulb Test wire found in some GM vehicles.
2 Pin Blue Connector :
Programming Switch
Route the gray and black wires in the 2 pin connector from the previously installed programming switch to the
control module and plug it into the mating blue connector on the side of the module.
3 Pin Antenna/Receiver Connector:
(White Connector)
Plug the previously routed three pin connector from the antenna receiver assemble into the mating connector of
the control module. This connector supplies 12 volts, ground and RF data from the antenna receiver to the
remote start module. Be certain this connector is firmly seated making good contact to the control system.
