Door pin switch circuit
The best places to test for the door switch wire are:
Pin switch
When testing at the pin switch, check the wire to ensure that it “sees” all the
doors. Often, the passenger switch will cover all the doors even if the driver’s
switch will not.
Dome light
This may not be your best choice if the vehicle has delayed dome light supervi-
sion, but it will work in any vehicle with completely diode-isolated or normally-
closed pin switches.
Once you have determined the wire color, the easiest place to connect to the
wire is likely the kick panel, at the windshield pillar - or in the running board.
When an easy location is not available, running a wire to the dome light is the
best alternative.
How to find a door pin switch trigger wire with your multi meter:
Set to DCV or DC voltage (12V or 20V is fine).
If you are looking for a positive circuit fasten the (-) probe of the meter
to chassis ground. If you are looking for a negative circuit, fasten the (+)
probe of your meter to (+)12V constant.
Probe the wire you suspect of being the door trigger wire. If the meter reads
(+)12V when any door is opened, you have found a trigger wire.
Note:
To ensure the wire “sees” all the doors, open each door and check the
meter reading.
