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.
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 2 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 2 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 2 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.

3 Wire Positive Switched Door Locks:
In this application, the Red wire of the two pin harness provides a + 12 volt pulse during the disarming sequence, or
pulsed 12 volt unlock output. Connect the Red wire to the low current 12 volt signal wire from the factory door unlock
switch to the factory door unlock relay.
The Green wire of the two pin harness provides a + 12 volt pulse during the arming sequence or pulsed 12 volt lock
output. Connect the Green wire to the low current 12 volt signal wire from the factory door lock switch to the factory
door lock relay. See Below For Wiring Detail.
