my tail light wires are cut and rigged with different color wires, and they dont work. How do I wire them correctly?

Hi smatthew! I couldn't find an available wiring digaram on the web so I will refer you to either your local library where you'll find the Chilton's for your F150 (hoepfully they have the individual version, the bound version may not have what you need) or your local Chevy dealer where the service manager may be able to get you some reference material as to the wiring diagram. You can also try Ford F150 Net (http://www.fordf150.net/) where there are plenty of resources to steer you in the right direction. Good luck!

Determine which side receives power from the front. It will jump to the other side side. Since the wires were cut I suspect there is a problem with the ground. No ground, no lights. Use a multimeter and probe to first determine power is being supplied to the side fed by the appropriate switch/pedal from the front. Check the fuse box making sure whoever cut then spliced in the wires did not blow a fuse. The owners manual should show which fuse operates the tail lights.
