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 control harness. CURT quick plug brake control harnesses make the installation of your brake controller literally a snap. They are designed to allow your brake control to plug directly into your vehicles power system using an original equipment connector. They are equipped with two plugs -- one that snaps into your vehicles original equipment socket and the other that connects to any CURT brake controller, including Venturer, Discovery, Reflex and TriFlex. CURT quick plug harnesses install in less than 10 minutes to get you setup and on your way with time to spare. They include two feet of wire and a slit loom sleeve to keep wires well protected and contained. This brake control adapter harness is compatible with certain years of the Chevrolet Silverado and GMC Sierra. For a complete listing of vehicle compatibility, see the CURT application guide or visit curtmfg.com.
