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. CURT quick plug brake controller harnesses make the installation of your brake controller literally a snap. They are designed to allow your brake controller to plug directly into your vehicle's power system using an original equipment connector. They are equipped with two plugs -- one that snaps into your vehicle's original equipment socket and the other that connects to a CURT brake controller. CURT quick plug harnesses install in less than 10 minutes to get you setup and on your way with time to spare.
