Finding A Parking Light Wire - Viper 330V Installation Manual

finding a parking light 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 available in the kick panel or running board.
(+) parking light wire
Use the following procedure to find (+) parking light 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

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 doesn't, probe
another wire.
5. Now turn the key to the start position. The meter dis-
play 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.
