asked by: Doug C
Expert Reply:
Hey Doug, the brake controller I recommend for your 2012 Mercedes Benz ML350 Bluetec would be the Curt Triflex kit part # C24GJ which comes with the correct install harness to easily install it. The harness plugs in under the dash and the other end into the back of the brake controller. The Triflex brake controller is a proportional brake controller too which means that it senses how hard you are applying the vehicle brakes and applies a relative amount of trailer brakes too which makes for smoother and safer stopping.
