Draw-Tite, iStop 20191 Electronic Trailer Brake Control for up to 3 braking axles WITHOUT the wiring. "Plug & Play" port matches all existing wiring adapters. Was used with a small trailer but can be used with much bigger trailers. Was removed when we sold the car last week (April 16, 2019) and is still in excellent condition. Buyer would have to purchase wiring and fittings for vehicle.
