Curt Trailer Brake Controller Harness, Select Cadillac, Chevrolet, GMC - 51525

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 with plug-and-play convenience 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 controller adapter harness is compatible with certain years of the Cadillac Escalade and Chevrolet Silverado / GMC Sierra 1500, 2500 HD and 3500 HD, Tahoe, Suburban, Yukon and Yukon XL. For a complete listing of vehicle compatibility, see the CURT application guide.
