CURT Custom Wiring provides everything you need to connect your vehicle’s electrical system to a trailer. With plug-and-play connectors, a custom wiring harness easily integrates with your vehicle taillights to provide a standard trailer wiring connector, typically in the form of a 4-way flat.
This custom wiring connector features a vehicle-specific design to perfectly fit certain years of the Nissan Frontier, Nissan Pathfinder, Nissan Xterra, and Suzuki Equator.
