DARK GREEN/ORANGE Wire: Tach SensorInput
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.

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 vehicle door lock / unlock circuits. The output of these wires has a maximum switching capability
of 300mA. Many vehicles today have factory door lock relays which can be connected directly to these
outputs, however always confirm that the factory relays in your particular vehicle do not exceed the rated
300mA output of the units door lock/unlock circuit. Plug the two pin connector of the door lock/unlock
harness into the mating connector shell of the control module. Determine the door lock circuit of the vehicle
you are working on and wire according to the diagrams shown.
3 Wire Ground Switched Door Lock Circuits:
In this application, the Red wire of the two pin harness provides a ground pulse during the arming sequence,
or pulsed ground lock output. Connect the Red wire to the low current ground signal wire from the factory
door lock switch to the factory door lock relay.
The Green wire of the two pin harness provides a ground pulse during the disarming sequence, or pulsed
ground unlock output. Connect the Green wire to the low current ground signal wire from the factory door
unlock switch to the factory door unlock relay. See Below For Wiring Detail.
