Have all the wiring previous owner kept controller any good brands?
I agree I run the Best, I went to the max brake when i put the disk brakes on my 5th wheel It works great with disk and reg. eletric brakes.This is what I run and love it, it has a ton of features that make towing a breeze as well as diagnostics of system if something goes wrong.

Now if you want the best you basically can only get it on-line and will cost about twice as much but it is a good step better. If I had time to have waited I would have ordered this one http://www.southwestwheel.com/store/p-3084-maxbrake-brake-controller.aspx
