I have a Tekonsha brake controller that I re-used on my 2017 ACE 30.1. The F-53 has a brake connector harness that was tied up near the parking brake. I bought a wiring adaptor that plugs into the Ford connector and Tekonsha connector. Mounted the brake controller on the lower right of the steering wheel on the dash.
I use an American Car Dolly towing a Mini Cooper S. We originally had the dolly mounted brake controller. However I found this controller to be very sensitive, with a lot of brake grabbing at slow speeds on pavement and wheel lock up on gravel, even when it was set to minimum gain. When entering a campground, I had to get out of the coach and go back and manually turn off the brake controller.
So I removed it and rewired the dolly to bypass it. Now I can adjust sensitivity, or even turn off the controller, from the driverís seat
