CURT 51451 is a 24-inch quick-plug electric trailer brake-controller harness for compatible Cadillac, Chevrolet and GMC vehicles with the matching factory OEM brake-control socket. This is CURT's bulk-packaged configuration of the harness, not a brake controller.
- Two plug ends connect the vehicle's original brake-controller wiring socket to a compatible CURT brake controller without cutting or splicing.
- Uses 12-gauge wiring with standardized wire colours and a protective slit-loom sleeve; the harness is approximately 24 inches long.
- Check the exact manufacturer vehicle table and OEM connection before ordering. A factory brake-controller socket and compatible CURT controller are required.
Key Features
- Designed for Any Curt Trailer Brake Control Systems.
- Configuration: Direct plug-in CURT brake-controller harness; bulk.
