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. This brake controller adapter harness is designed to allow competitor brake control harnesses to be used with CURT trailer brake controllers. It is compatible with Tekonsha, Reese, Draw-Tite and Pro Series vehicle-specific harnesses (The brands listed are registered trademarks of Horizon Global).
