For a brake controller designed to be installed on a vehicle with air brakes to control the electric brakes of a trailer you would want the Brake Controller # HA100400C.
This controller will be able to sense the amount of braking pressure you are applying and will correctly apply the trailer brakes in proportion to this.
I attached a review video for you to check out for this controller as well.
