Steve, it sounds like the receiver brake light uses a logic circuit like that JC Whitney one. There is no surefire way to get a real brake signal with just a 4 wire harness. On my old car I used the CHMSL signal to go to one of the extra pins in the 9 wire plug. (On an older car with no CHMSL, you could just go off the wire at the brake pedal switch, that's where they tapped for the CHMSL anyway.) Actually I liked the 9 wire plug better anyway because it is the same size and shape as the 7 wire, but is much more solid and secure because it uses round pins instead of blades.

I do not know how the older models where wired up. I think they have sheet metal on the bottom and the harness may be above that.

John, at least on mine, it is assembled just like you say. There is a black waterproof membrane on top of the steel frame, and the camper is built onto that. The wiring and gas lines go below the membrane so it is easy to get at. I just ran one wire from the extra Hydrastar wire and bundled it with the rest of the harness. The ground I attached to an existing frame ground that was very close to where my wire exited the floor.
