I'll watch that youtube, but I found a few holes drilled in the HVAC vent that shoots air at drivers feet. I think that was were a brake controller was mounted. I still don't understand the need for an aftermarket controller when this truck came factory with one. I understand some will say they aren't as good and maybe that's the case.....I don't have enough experience with that, especially with this truck. A buddy has a 2015 3/4 ton pickup and he hauls a dump trailer with brakes and says his works great.

Hole in dash unexplained still, likely a toggle but for what....there's holes in the cargo area, that I think maybe they had a permanent mounted cooler, so maybe they had that on toggle. Those wires should be somewhere if so. That is still a guess at best.
