When I got my truck, I was wiring it up for the RV camera system. I was having issues finding a entrance into the cab. I talked to the service manager at the dealer. He told me where I could get the wiring into the cab. He also told me, that if there was ever a major engine problem, they lift the whole cab off the truck frame. So, I made up a harness for the cameras with quick connects, just in case.
