Silverado Running Light Wire Color. Might be something similar in your truck. But when I did it I found out which wires under the dash were for the signal lights with a test light.
Might be something similar in your truck. Hmm ok so it won't be the same. Links below: In this video I show how to wire a led light bar into a chevrolet silverado, It can be done roughly the same with other trucks.
These switches have two light-colored A new cable with a black, a white, and a ground wire is run from the fixture box to a newly installed switch.
Trying to setup a backup camera to my HU, and the HU has a reverse wire that you just splice into your reverse light wire.
Not ideal for external wires but I feel like it's ok for interior wires. When the truck is running, when I put it in reverse, it seems as though a circuit "trips" and both the LED frame AND both reverse lights go out. Running, brake, left and right turns and back-up?
