My lights aren't working and the fuses are good and the bulbs are brand new.

I looked under my truck and found this connector that plugs into the transmission mashed up and was zipped tied to the frame.

I am thinking someone broke the connector when I had my tcase redone a month ago.

But I am wondering if that connector has anything to do with the reverse lights?? It's the only thing I can think of as I have multi metered the crap out of my truck...

 

Here's the connector attached to the tranny after I mashed it on...

 

That could well be the backup light switch. use a short jumper between the wires, turn on the key and see if the lights work if not check the fuse if yes replace the conecter and or the switch

 

That is the reverse light switch.

 

Thanks Sean, how should I fix it?

 

Not sure how the switch works. If it's a contact switch, which 2 wire usually are, then jumping the wires will make the reverse lights come on with the key on. If not, not a switch problem.

 

The switches wear out, mine come on after rolling a few feet in rev, sometimes shift it into rev more than once to get them to work, try cleaning the connections if you can and try that. If not try checking that harness. I haven't tried pulling the switch out yet to see about replacing it.

 

If you jumper the connector and the lights come on almost certainly your problem is with the switch itself. The switch should be inexpensive and easy to change. Its most likely a contact type switch , that when the monkey motion inside the case contacts it the switch closes, the circuit is completed and the lights come on. I doubt the monkey motion is the source of the problem.

 

If you jump the wires and it works just splice in a switch up in the dash. Anytime you need it- turn it on.
(scares the hell out of people if you turn it on as the light turns green, LOL _

 

It was a switch problem. I jumped it and they worked so I am going to try and heat up the connector, push it on and electrical tape it there for now. Thanks all!
