Question about 1983 Chevrolet C3500
How do you re-wire a box truck for tail and brake lights?
The wire harness for the back lights comes in 2 pieces. Undo the center bolt at the fuse panel on the engine side of the firewall and pull the left side wire harness off the fuse box. That is the one that goes to the back of the truck. There is one wire in it that you will have to cut because it doesn't go all the way back. The second connector is under the box near the rear bumper on the driver's side. It runs to the lights from the first harness. It is prone to corrosion and may be your problem. If it is just cut it out and splice the wires together, using connectors and heat shrink tube. Then tape over the tubing and you should be good. Chevy tail lights are also prone to chaffing inside the box at the tail light so if you are haveing trouble check for that. Just tape them up and repostion them so they don't chafe. Also check the ground wires at the back. They very often rot off or stop making a good connection from years of road crud. The light sockets are available at any auto parts store if you need them. Hope this helps.
