It takes a lot of power to stop a moving trailer, especially when that trailer is hauling livestock, construction materials, industrial equipment or other heavy duty cargo. Play it safe when you tow and give your trailer brakes the control they need with a CURT trailer brake controller and brake controller harness. This brake controller harness features an OEM plug to connect to the vehicle and has pigtails to splice into a brake controller. It features color coded wires to coordinate with the appropriate electrical functions and features two feet of wire for convenient installation.
