Description

The Curt 55540 is a custom wiring harness designed to connect your vehicle's electrical system to a trailer. It features plug-and-play connectors that integrate with your vehicle's taillights to provide a standard 4-way flat trailer wiring connector. This harness is specifically designed for certain years of the Chevy Express and GMC Savana 1500, 2500, 3500, and 4500 models.

It utilizes OEM-compatible connectors to "T" into the vehicle's taillight assembly, offering a 4-way flat output for trailer taillights, brake lights, and turn signals. The harness includes a rubber dust cover to protect the connection points when not in use and can be conveniently mounted to a trailer hitch receiver tube with a CURT Easy-Mount connector bracket.
