First off my driver side brake light with stop working. I took it apart to try and find the short. In the process I shorted out all my running lights tail lights and brake lights and turn signals I think also. While I was looking for the short, turn signal wire from my tail light touched the frame and grounded out and that's when all the lights died . My tail lights are some cheap trailer lights without reverse lights. I pulled headlight switch from another Ford truck I have. On the harness connector that connects to the switch which wires should read what when I test with a voltmeter?I checked the fuses in the power distribution box under the hood and they were good. Truck has a flat bed so I don't know if that matters with the wiring, I suspect it's different then a normal bed truck. Wiring on the bed is old, maybe from 94. I am unexperienced with electrical, so if anyone knows an easy way to find a short please let me know.

 

On the headlight switch connector, the power for the running lights comes in on the tan/white, and leaves on the brown wire. There should be a fuse in the underdash fuse box for the tan/white wire.

There will also be fuses for the turnsignal lights and the brake light circuit. Check in the underdash fuse box.

 

Thanks, I'll check them this morning.

 

also, if the lights are not bolted to the truck they will not work properly. there is no ground wire in the wires, the ground comes from mounting the light to the truck.
