Rear 7 pin was not hot from the factory. Searched and found thread about installing fuse. Worked great. Also read about trailer wiring between bed and the cab. I found this also.
1) The wires were bundled, but wouldn't come down. I'm guessing its already run to the factory installed 7 pin on the bumper? Or, is the wiring for something else? I figure if its bundled, maybe its not installed?
2) Hot wire now works with the fuse installed, but is still hot when the key is off. If I pull the fuse, its not hot, so I know its the right one. Any way to make this wire key on hot only? I have a truck camper and plug in the camper before I fully lower it into the bed. Thus, I'd have to lower legs and unhook the camper tie downs just to pull the plug. What a pain since I often don't unload my truck camper. I don't want dead batteries when I camp for several days.
