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 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 any CURT brake controller, including Venture, Discovery, Reflex and TriFlex. This brake control adapter harness is compatible with certain years of the Ford Windstar, Ford Bronco, Ford Econoline van, Ford Excursion, Ford Expedition, Ford Explorer, Ford F150, F250, F350, Ford Flex, Land Rover LR3, LR4, Range Rover, Range Rover Evoque, Lincoln Mark LT, Lincoln MKT, Lincoln Navigator and Mercury Mountaineer.
