How to find (+)12V ignition with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the ignition wire. The steering column harness or ignition switch harness
is an excellent place to find this wire.
4. Turn the ignition key switch to the run position. If your meter reads (+)12V, go to the next step. If it does
not read (+)12V, probe another wire.
5. Now turn the key to the start position. The meter display should stay steady, not dropping by more than a
few tenths of a volt. If it drops close to or all the way to zero, go back to step 3. If it stays steady at (+)12V,
you have found an ignition wire.
The (+) parking light wire is often found near the switch. Many cars have the switch built into the turn signal
lever, and in these cars the parking light wire can be found in the steering column. The same wire is often avail-
able in the kick panel or running board.
How to find a (+) parking light flash wire with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the parking light wire. Usually, the area near the headlight/parking light
switch is an excellent area to start, as is the kick panel.
4. Turn on the parking lights. If your meter shows (+)12V, turn off the parking lights and make sure it goes back
to zero.
5. If it does return to zero, turn the parking lights back on and, using the dash light dimmer control, turn the
brightness of the dash lights up and down. If the meter changes more than a volt when using the dimmer,
look for another wire. If it stays relatively close to (+)12V, you have found your parking light wire.
