To install a brake controller in your 2015 Four Winds Majesty will require a brake controller like the BRAKE-EVN part # TK63VR, the install harness # 3034-P and the 4-way to 7-way adapter part # 37185.

The # 37185 plugs in to your current 4-way and then from the blue wire of it you'd run a length of 10 gauge wire like part # 10-1-1 which is sold by the foot up to the blue wire of the brake controller.

The black wire of the adapter runs up to the positive post of your battery with 10 gauge wire and the left over wire then would run to a reverse light circuit to activate the trailer reverse lights.
