From my experience the trailer brake control only feeds the brake signal to the back trailer outlet on the vehicle. I dont think any of that wiring will be useful if hooking up the vehicle to a rv.
Basically you need to get tow bar (or tow trailer), brakes, and lights.
Several ways to do that and allot of different opinions on the different options.
I had a master tow dolly with electric brakes and add on tow lights - That was ok and probably the cheapest way to go. But I decided to go to flat tow thinking it would be a lot easier and more convenient - so far it has been.
Picking up good deals on used and including the brake unit rebuild I probably have close to 1000.00 in to it. The Explorer I bought already was wired for lights and had the tow brackets on it.
If I had allot of money I would probably opt for a different set up - But I have to watch my penny's - Especialy if I want to get a new Born Free someday -
