Installation of Electric Brake Controller in Entegra Motorhome Prewired with 7-Way Trailer Connecter

Question:

Is there a specific harness or anything special needed to use this equipment with a coach with air brakes? What does the dash mounting hardware look like?

The Redarc Tow-Pro Elite Trailer Brake Controller - 1 to 3 Axles - Proportional # RED44FR will work with a 7-way prewired without any issues. As long as the brake light switch, 12V power, and Brake output wire are all working you can absolutely use that controller even with your air brake system. I've attached photos to assist with mounting the braking system as well as the installation instructions.

If you don't have the wiring diagram you can determine the wire functions by using a circuit tester like # PTW2993. The red wire will connect to the cold side brake light switch, the black wire to 12V power, the white wire to ground and the blue wire to brake controller output at your 7-way.
