I'm trying to provide power to my slide in camper via the wiring harness Chevy provides which is located under the bed of the truck, toward the front of the bed, on the driver's side. The harness has everything for a 5th wheel (turn indicators, brake controller, etc), but I only want +12V and ground. Both the manual and the label that is on the harness indicate that white is ground and red is battery. I've verified the ground (white) wire is a good ground and that the battery (red) wire isn't providing +12 volts. I checked the fuse block under the hood on the drivers side and the fuse that's labeled as "trailer bat" looks good. It's dark out and I'm tired of holding a flashlight and a multimeter. I plan to resume and/or contact the dealer in the morning, but wondered if someone here might have the answer before then.
Thanks in advance. Because I'm starting a 10 day trip some time tomorrow, whether I have power to the camper or not, I might not see and/or reply to any answers until my return. This is kind of a "shot in the dark" (pun intended) post.
