2010 2500hd rear trailer harness
After removing my gas tank tonight, I found part of the rear coupler harness folded up. It was zipped tied, wrapped with blue tape and ends sealed with shrink wrap. It comes from the rear trailer light coupler. Does anyone have any clue what this is for? It has strap holders installed and looks like they where never installed into holes in the frame. Thanks Mike

It looks like it would continue up frame rail to front of truck. At the rear of the truck it splits. Half goes to coupler, the other goes to some other wire/coupler then to the rear electrical block. So puzzled.
