Connect your REDARC Tow-Pro™ Elite or Tow-Pro™ Liberty electric brake controller with a vehicle specific brake controller wiring harness. This Tow-Pro wiring harness easily connects into GMC, Cadillac or Chevrolet factory towing package connector behind your vehicle dash. Apply the plug and play design and follow fitting instructions. Included loom with compatible connector allows you to simply plug one end of the harness to the electric brake controller connector and then plug the other end to the factory fitted connector behind the vehicle dash. The Tow-Pro Liberty does not have a mating connector and requires bare wires to be inserted into the brake controller instead.
