A CURT Quick Plug brake controller wiring adapter is one of the fastest and easiest ways to plug your brake controller into your vehicle. It requires no cutting or splicing! Just insert the vehicle-specific plug end into the OEM vehicle?s factory brake controller socket. The other end plugs into your CURT trailer brake controller. Quick Plug harnesses are available for a variety of vehicles and are unique for each vehicle application to provide the easiest possible installation. This particular brake controller harness fits certain years of the Ram 1500, 1500 Classic, 2500, 3500, 4500 and 5500 (without factory integrated brake controller ITBC) (see application info to verify fitment). CURT Quick Plug harnesses are compatible with most CURT brake controls and can be used as a replacement or for a new control unit installation. They're also great for towing all types of trailers with electric brakes. For versatile mounting of your trailer brake controller this Quick Plug wire harness measures two feet long. It also features a slit loom sleeve to keep the wires protected against crushing and abrasions. CURT Quick Plug wire plug-in adapters are made with 12-gauge wires for a reliable connection and braking, and come with zip ties to keep the harness contained and out of sight. NOTE: Software in vehicle must be updated by dealership in order to accept an aftermarket brake controller. Failure to update may result in damage to vehicle.
