power wire, or the (+) terminal of the battery.
3.Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resis- tance in one direction, no resistor is needed for that direction.
4.Once the resistor value(s) is determined, refer to the wiring dia- gram for proper wiring.
