Trailer Backup Lights - Wiring not Working

[dhcomp]

I'll look up the gm schematic for this when I get back to work and see what it shows

Awesome. Thanks!

Annnnnnddddd I forgot. I'll try to remember tomorrow.

Both are basically the same. So you won't have power on the trailer back up fuse unless the key is on and the trans is in reverse.

Thanks. With truck on and in reverse, i have no power at the fuse. Wonder what isn't connected, if the regular backup lights work fine.

It is odd. Best bet would be to pull the fuse box up and try to trace the wires under there.
