2005 Yukon XL 2500 tow wiring 12v at truck hitch?
I have a 05 Yukon Xl 2500 with tow package but the 12V constant is not hooked up. I talked to the service writers at my local dealer and they said I need to make apmt. I heard it was just a matter of hooking up one wire. it has nothing in the manuel about it. and I don't see anything in the fuse box. I have pulled both and can't find anything not hooked up.
Any help would be super..Thanks
