DOOR LOCK WIRING
Reverse Polarity: Many Ford/Lincoln/Mercury/Dodge/Chrysler/Plymouth and early 90’s GM Trucks
Reverse Polarity systems use no relays, but instead the door lock/unlock motors are controlled directly from the lock
and unlock switches in the door. The lock and unlock wires rest at Negative Ground when not in use. When the
lock or unlock button is pressed, one of the circuits is “Lifted” and replaced with +12V causing a lock or unlock to
occur.
