Description

The CURT 51531 is a universal trailer brake controller harness designed to connect a brake controller to a vehicle's electrical system. This harness splices into the vehicle, offering a quick plug connection for your brake controller. It is compatible with any CURT brake control and helps eliminate backfeed on brake lights. The harness reduces input voltage for optimal brake controller function and features wire colors that match standard brake controller harnesses. It includes 24" of 12-gauge wire and a protective slit-loom sleeve for installation.
