1985 Jeep Cj7 Headlight Switch Wiring Diagram

Early Jeep owners have long admired the iconic 1985 Jeep CJ7 for its rugged capability and classic style. As Jeep enthusiasts know, though, the CJ7's headlight switch wiring diagram can be tricky to navigate. Understanding the diagram is essential for performing routine maintenance and repairs on the CJ7.

At first glance, the headlight switch wiring of the 1985 Jeep CJ7 can appear intimidating, but this wiring diagram is relatively straightforward once you take the time to understand it. The 1985 Jeep CJ7 uses a two-pronged, four-position light switch. This switch has four power sources that control the workings of the entire vehicle-side lighting system.

The first two power sources are sent from the alternator to the battery via the red wire and then to the light switch. These two wires provide power to the tail lights, the left turn signal and the right turn signals. The third power source is given off by the ignition switch, which is powered by the coil wire. This provides power to the headlights, the parking lights, and the high beam indicator. Finally, the fourth power source comes from the switch itself, running through the black wire and providing power to the dimmer switch and wiper switch.

With this wiring diagram in hand, it's easy to troubleshoot any problems with the lighting system of your CJ7. Basic continuity testing is all that's needed to pinpoint faulty switches and wiring, and most repairs can be done in a matter of minutes. Wrangling the headlight switch wiring of your 1985 Jeep CJ7 may seem daunting at first, but with a bit of patience and a proper understanding of the diagram, it's easy to keep your vehicle's lights functioning properly.
