Trailer wiring extension into bed acting funny!
I apologize now as this is second hand information on my BIL's truck, a 2016 6.7l.
He has just installed a trailer wiring extension into the bed of his truck. From what I understand, he's pulled the connector off behind the bumper, put in this new extension, and plugged it back into the factory bumper connector. Then ran the new wiring to the bed to use with his gooseneck.
So, from what I gather, if you plug the trailer directly into the new wiring location, nothing works and there are faults on the instrument cluster. However, if you plug it into the bumper location, the faults go away and everything works. If you again, move the plug to the bed location everything STILL works for a while.
I am not sure what causes the bed plug to stop working (turn truck off or unplug trailer??) and I can get that information, but it sounds like it happens often enough that he can't just keep moving the plug to get it all to work.
He's tested all the wiring with a meter to make sure all the wires or connected properly between the factory and the new extension. Seems like a computer issue of some sort not wanting to recognize the new location?? Any ideas? Thanks!
