CURT custom wiring harnesses provide everything you need to connect your vehicle's electrical system to a trailer. With plug-and-play connectors, they easily integrate with your vehicle taillights to provide a standard trailer wiring connector, typically in the form of a 4-way flat. CURT custom wiring harnesses feature a vehicle-specific design to perfectly fit certain years of vehicles and use OEM-compatible connectors to "T" into the vehicle's taillight assembly providing a standard 4-way flat output to power the taillights, brake lights, and turn signals on your trailer.
