cases will operate properly from one multi coil pack regardless of the number of cylinders. If the vehicle has a

single coil unit for each cylinder, it may be necessary to connect this wire to more than one cylinder for proper tach

reference. See multi coil wiring detail shown later in this manual for additional information.

Tachometer Input Wiring Detail

Green/Yellow Wire: Diesel Wait To Start Input

The Green/Yellow wire will connect to a diesel vehicles glow plug wire. When the unit receives a start command,

this wire must go to + 12 then to ground to allow the crank sequence to begin. When ignition #1 is activated by the

remote start unit, the glow plug circuit gets energized, (+ 12 volts), when the glow plug circuit of the vehicle drops the

+ 12 volts, which effectively grounds the wait to start input, then 500mS later the starter will engage. This wire can

also be connected to the Glow Plug Bulb wire in the vehicle if this bulb wire gets + 12 volts when the ignition comes

on and drops low when the glow plug circuits temperature is reached. Be sure to fuse the wire with a 1 Amp Fuse

when connecting to a high current circuit such as a factory glow plug wire. The fuse should be installed as close

to the high current wire as possible. If you are installing this unit in a Gasoline vehicle, this wire is not used.

WIRING THE 4 PIN AUXILIARY OUTPUT HARNESS

The auxiliary 4 pin connector provides low current outputs to control various functions in the vehicle during

different stages of the Remote Start unit'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.

Black w Blue Trace Wire: Pulsed Ground Output Before Start

The Black w/ Blue Trace wire will provide a 1 second 300 mA pulsed ground output 1.5 second before the

remote start unit activates as well as when the transmitter is used to 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 unit engages or when the transmitter is used to unlock the doors.

Black w/ Light Green Trace Wire: Pulsed Ground Output After Start

The Black w/ Light Green Trace wire will provide a 1 second 300mA pulsed ground output after the vehicle is

started under control of the remote start unit. 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 Trace Wire: Pulsed Ground Output After Shutdown

The Black w/ Red Trace wire will provide a 1 second 300 mA pulsed ground output after the remote start unit

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 Trace Wire: Ground Output During Start (Crank)

The Black w/ Yellow Trace wire will provide a 300 mA ground output while the starter output of the remote

start unit is active. This output can be used to activate the Crank Low/Bulb Test wire found in some GM

vehicles. This wire is also referred to as the ECM wake up wire in some Chrysler vehicles.

NOTE: The outputs above are low current outputs and must be used with a relay if the circuit's requirement

is more than 300 mA.

Push-Button LED Programming Switch Assembly: (2 Pin Blue & 2 Pin White Connectors)

Route the gray and black wires in the 2 pin connector and the red and blue in the two pin connector from the previously

installed push-button LED programming switch assembly to the control module and plug these into the mating blue

and white connectors on the side of the module.
