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 comes with 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 comes with two feet of wire for convenient installation. This splice-in harness also comes with a protective slit loom sleeve and can easily be installed using CURT snap locks. It is designed to be compatible with certain years of the Ford F250 or F350 Super Duty and F450 or F550 Super Duty. For a complete listing of vehicle compatibility, see the CURT application guide or visit curtmfg.com.
