1.
Cut the output wire from the door lock switch/key cylinder.
2.
Test with the meter from the switch side of the cut door lock
switch/key cylinder wire to a reliable constant (+)12V source.
Some good constant (+)12V references are the power input
source to the door lock switch/key cylinder, the ignition switch
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.
