Wired Harnesses 55550 CURT 4-Pin Custom Trailer Wiring Harness T-Connector 4-Way Flat

The CURT 55550 is a vehicle-specific, plug-and-play trailer wiring harness — also known as a T-connector — designed to connect select Kia Sorento vehicles to a trailer's lighting system without any cutting, splicing, or soldering. It plugs directly into the vehicle's existing OEM socket and delivers a standard 4-way flat output to power your trailer's taillights, brake lights, and turn signals.

Built with surface mount technology (SMT) circuitry, this harness generates less heat, maintains optimal light intensity, and delivers long-lasting, reliable performance. A tail light converter is included to ensure full vehicle-to-trailer electrical compatibility.

Key Features:

• Plug-and-play design — no cutting or splicing required

• 4-way flat output powers taillights, brake lights, and turn signals
• Equipped with a built-in tail light converter for vehicle-trailer compatibility
