On my rig, I had quite a few wires that had fallen down and were caught in the engine cowl (the doghouse). I had that cover off to add some insulation and while I did, I secured many of the wires up out of the way. I had that cover off again recently and found some I had missed, so I secured those out of the way as well.
Anyway, the original wiring that was hanging down very well could have been the camera wiring; it was hanging in the direct top middle, right under the head unit. I didn't bother checking WHAT it was, I just zip-tied it out of the way. It was blocking the seal between the cowl and the sheet metal for the opening which was allowing MASSIVE amounts of heat into the passenger compartment...
