Trying to Install a Factory 3rd brake light on the back of my Go Fast Camper without taking the camper shell off to do it.. Anyone know where i can tap into the original harness from the 3rd brake light? The original on the back of the cab is still there and unplugged, i just unplugged the wires to the diodes in the brake light so i didn't get brake lights kicked back into the cab off the camper. Trouble finding a wiring diagram to see which pillar it goes down and i haven't had luck finding it after tearing some of the truck apart. The only thing left to do is pulling down the head liner to access the harness but I really dont want to do that either!!
Thoughts? Diagrams?...
