3 Wire Ground Switched 2 Step Door Locks
In this application, the Red Wire provides a ground pulse during arming or locking, connect the red wire
to the wire that provides a low current ground signal from the factory door lock switch to the factory door
lock control relay.
The Green Wire provides the rst ground pulse during disarming or unlocking, connect this wire to the
drivers door unlock relay that requires a low current ground signal to unlock only the drivers door.
If the vehicle does not have a separate drivers door relay, one will have to be added. Locate the drivers
door unlock motor wire and cut it at a convenient location to allow wiring of an optional relay.
Connect the door side of the cut wire to terminal #30 of the optional relay added.
Connect the vehicle side of the cut wire to terminal #87a of the optional relay added.
Connect the green wire of the 3 pin harness to terminal #86 of the optional relay added.
Connect terminal #85 of the optional relay added to a fused constant +12 Volt source.
Most vehicles door lock/unlock motor legs rest at ground, and switch +12 Volts to the door lock/unlock
motor legs for operation, if this is the case in the vehicle you are working on, connect the remaining
terminal, #87, to a fused +12 Volt source.
In the rare instance that the vehicle door lock/unlock motor legs rest at +12 Volts and switches ground to
the door lock/unlock motors, connect he remaining terminal, #87, to chassis ground.
The Red/Black Wire provides a pulse ground output when the unlock button of the transmitter is pressed
a second time after disarming.
Connect the Red/Black Wire to the wire that provides a low current ground signal from the factory door
unlock switch to the factory door lock control relay.
