anyone have the wire diagram for the trailer light plug ins? 2010 is the year.

truck is new to me, and hooked up today and only got running lights. No brakes, no signals, lights just stay on. They worked great on my lightning last time i used my trailer.

since then, i let it sit for a while and decided today to rewire it. Finished complete replacment, and still only running lights, so im thinking the previous owner might have something to do with them not working.

no power on the yellow or green out of truck.

:specialed:

Did you install the relay and fuse that was in the glove box from the factory?

My running lights wouldn't work because fuse 67 blew, I don't know if that's relevant to your issue or not though

There should be one relay and one fuse for the trailer stuff in the underhood fuse box, can't remember the socket numbers off hand but they will be listed in your owners manual.

10-4 they were installed.

found a 20 fuse blown in the box that lets the relay work.... replaced and checked and lights are back to working...

Thanks fellas!!
