Green/Orange Wire: Tach Sensor Input
This wire will continually monitor the engine tach rate while the unit is under power of the Remote Start module. 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 unit 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 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.
