Thanks again for the tips!

I found a solenoid under the bed that's only hot when the ignition switch is turned to the on position. Works out great. I can park for the night and the brake system only comes alive when I start it in the morning. That keeps it from drawing on the house batteries overnight. I always cross-check hookup, brake operation and directional before getting under way anyway. If it's raining, I'm basically screwed and get wet.

Your 7-pin will have a hot spot too. You'll need to find it with a voltmeter - if you can find a 7 pin for your towed. I couldn't and used a 5-pin. I ran separate power lines for the braking system using the solenoid and ran the lines through an existing passage under the bed. I used a coat hanger to ream out the foam a little to let the wires pass through. Connect that to the 4-pin on the coach side and viola. You probably see where this is going. If not ask.

Got the parts from O'Reilly's. Two 4-pin connectors, wiring conduit and 4ft of wire. I fab'd a holder for the coach so it's sits atop the 7-pin and bolted the other 4-pin to the roadmaster adapter bar.

I have the BO setup. Towing now for 11+k miles. Couldn't be happier with it. When not in use, I disconnect the wires and fold the tow bar back against the grill, secure it with bungie strap and a bicycle lock and off I go. I bought a toad wiring harness from etrailer and installed it on the truck in about 4hrs. It's neat, clean and wrapped front to back in plastic wiring conduit. I used zip ties where needed. Maybe some (or all) of this helps.
