Hello all been absent for awhile, got distracted by scuba and becoming an instructor. Now I am back to finish my bed restoration but am stuck on something very simple. I cannot get tail lights wiring figured out. I found two sets of wires under the bed. With the truck lights on three of the lines are hot. With the brake peddle depressed the fourth is hot. And my tail lights have two wires two bulbs, I took a battery and brought power to one wire and the other other terminal to the light case and the light lights, same thing going to the other wire. But when I bring just power no lights, I assume there is no ground. Is the ground normally just the physical connect to the truck bed and maybe the paint is preventing ground? Or I am I missing something more obvious? Thanks in advance, Denis
The tail light grounds through the housing to the bed. You should have power on the tail light wire only when lights are on, then power on the brake light wire when the brake is depressed. Is this an origional harness or aftermarket?
lights now working Not sure what I did wrong the first time but wired it up and all is working. Denis
