Please clarify. You posted in Class C and called your chassis F53. That's a Class A chassis. IF you have a Ford-based Class C, E350 or E450, then YES, there should be wiring for a Brake Controller.
I have installed them in Fords, just not E-Series. Should be a square plastic connector. By square I mean four terminals in a square pattern.
That said, I think I saw where E-Series had two connectors that looked alike. One was for Brake Controller and the other for something else. Two different colors of plastic. Gray and Brown if I recall, just forget which is which and what their locations are.
Enough OP's here have done it that you should have details soon. Given it's E-Series...
