I decided to put extra reverse lighting on my truck since the fab fours rear bumper I just put on has a nice spot for a light on each side. Wiring them right into the back up light wire is easy, but I want to be able to switch them on whenever I want for when i'm loading the trailer, or something into the bed at night.
So heres a clean way to do it.
Under the dash is the BCM. The green(lime) wire you see in the furthest right connector is the wire that goes to the reverse lights (pictured).
So I tapped into that wire which goes to one end of my switch.
For a hot source, I went to the junction box under the dash behind the emergency brake(pictured). In there I pluged into a prong that is hot all the time (pictured). I took this wire to the other end of the switch. Now, when i flip the switch the reverse lights come on. I tapped into that same green(lime) wire under the rear of the truck to feed the auxiliary lights, and just grounded them to the body. Now, the reverse lights as well as the aux. lights will come on whenever the truck is in reverse, or when i flip the switch.
This just saves having to run a wire from the cab to the aux. lights. Like I said, just a lil cleaner install. Hope it helps somebody.
