Need some electrical help with my ‘68 Plymouth Valiant 100
1 = Instrument lamps, dash lights, gear shift light, radio light - its path... main splice off the ammeter wiring to the headlight switch then runs through the dimmer in the headlight switch then to the fuse then to the bulbs.
2 = Tail lights, stop lights, dome lights - its path... main splice off the ammeter wiring to the fuse then to the bulbs.
3 = Cigarette Lighter - its path... It taps off of the Tail Light input IN the fuse block then runs through the fuse then to the cigarette lighter
4 = ACC RR - A/C = AC - Its Path... My wiring diagram does not have anything shown
5 = Heat A/C - Its Path... It taps off the Radio input IN the fuse block then through the fuse then to the heater switch. From the heater switch it goes to the heater blower motor.
6 = Radio - Its path... main splice off the ammeter wiring to the ignition switch then runs to the fuse block through the fuse then to the radio.
The input (heavy red wire) to #2 and #3 are always hot
The input (heavy black wire) to #5 and #6 are switched
you REALLY need to get a wiring diagram and start tracing wires
MyMopar has the wiring diagrams separately or in the FSMs or CLASSICCARWIRING.COM has colored wiring diagrams, very easy to follow, BUT some times is missing some things like the #4 fuse feed. (It does have a separate break out section for the AC wiring though)
