Tachometer Input Wiring Detail
Green/Yellow Wire: Diesel Wait To Start Input
The Green/Yellow wire of the 2 pin connector 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
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
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.
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
2 Pin Door Lock/Unlock Harness: (White Connector)
The Red & Green Door Lock/Unlock output wires provide either a pulsed ground or pulsed + 12 volts to control the
