Power Door Lock Connections:
Determine the Door Locking/Unlocking circuitry that your vehicle is equipped with. Fig. 2 shows the door lock/unlock
output relay & Pin number configuration of the C3 Control Module connector. The majority of vehicles come
equipped with either Neg (-) Fig. 3 or Pos. (+) Fig. 4 Trigger circuits. Find the location of the appropriate circuitry for
your vehicle (Make, Model, Year Diagrams can be found on our web site at www.GalloTech.com) If the Trigger wire
is 0v when the Lock/unlock switch is depressed then you have a Neg. (-) trigger (Fig. 3). If the trigger wire is +12v
when depressing the Lock/unlock switch then you have a Pos. (+) Trigger (Fig 4). For Pre- ’95 Audi or Mercedes
Benz vacuum motor operation use Fig. 5. For Reverse Polarity applications, were the lock and unlock wires rest at
Negative Ground, use Fig. 6.
