anyone have a wiring diagram of the back up lamp system? i have a 2005 silverado. the issue im having is that im getting power at the B/U fuse but not at the trailer b/u fuse or am i getting power from the rear connector, i know the lite green wire is for the back up lamps. however, everything else is working just fine....i got the truck off my friend a few months ago and he couldnt figure out the problem either.

thanks..

First thing I did when I got my truck was to grab a Helm manual. It has all the diagrams in it. There should be links to some on the main page down at the bottom.

You can download the full Chilton manual here

It has some wiring diagrams in the back.

Sounds like maybe you have a broken wire, if you can check and see where voltage is present on the green wire maybe you can trace it back and see where along the harness it broke.

Thanks I'll check it out more tomorrow

OK so its a pink wire and goes from the b/u lamp fuse to the switch at the transmission and comes out as lite green all the way to the rear.I believe there's a break between the switch and rear lights. Thanks again man. Really appreciate the diagram.
