This vehicle-specific adapter is one of the fastest and simplest ways to connect your brake controller without any cutting or splicing required.
Just plug one end into your vehicle's factory brake controller socket and the other into your CURT trailer brake controller for a perfect, hassle-free connection.
This harness is specially designed to fit select years of the Cadillac Escalade, Chevrolet Silverado and GMC Sierra 1500, 2500 HD and 3500 HD, Tahoe, Suburban, Yukon and Yukon XL.
It works great as a replacement or for a brand new installation and is compatible with most CURT brake controls, including proportional, inertia, and time delay models.

Whether you're towing a boat, camper, utility trailer, or horse trailer with electric brakes, this harness ensures reliable power delivery.

Built with quality 12-gauge wires for consistent, strong performance, the harness measures two feet long for flexible mounting options.

It features a protective slit loom sleeve to guard against crushing and abrasions, plus zip ties to keep everything neat and out of sight.
You get reliable power between your controller, vehicle, and trailer brakes every time.

No more complicated wiring jobs or worrying about poor connections.
