I have posted several times about getting and older SAT dish to work. Solved the problem today by buying another coach. The "new" coach is a 07 HR ambasador. It does not have a brake controller for a ...
Installing a brake controller can be easy (already have a receptacle somewhere under the dash) or somewhat difficult....(splice wires and find out what does what)...then running that wiring harness to the back of the motorhome...and choosing a flat 4, round 5 or round 7 for the trailer to plug into.
My suggestion: if you have to splice wires...get a shop to do it. Not necesarilly a RV dealer....any trailer shop can do it...probably cheaper. And 100 bucks labor? IMO, well spent.
