If one resistor is used in the door lock switch/key cylinder, the wire will pulse (+)12V in one direction and less
than (+)12V when operated in the opposite direction.
If two resistors are used in the factory door lock switch/key cylinder, the switch/key cylinder will read less than
(+)12V in both directions.
To determine the resistor values, the door lock switch/key cylinder must be isolated from the factory door lock
system. For all testing, use a calibrated digital multimeter that is set to ohms.
1. Cut the output wire from the door lock switch/key cylinder in half.
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 multi-
meter displays zero resistance in one direction, no resistor is needed for that direction.
4. Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.
