7 Pole Connector Car Side

The CURT Manufacturing 7 Pole Connector Car Side (Model 58151) is a universal vehicle-end trailer plug designed to establish reliable electrical connection between a towing vehicle and trailer lighting systems. This seven-pin socket connector accommodates the full range of trailer functions—brake lights, running lights, left and right turn signals, reverse lights, and auxiliary power circuits—making it the industry standard for most medium and heavy-duty towing applications.

Constructed from durable black plastic housing, the 58151 connector resists UV degradation and moisture intrusion during extended outdoor use. The universal design accepts standard seven-pin trailer plugs without modification, ensuring compatibility across domestic and import vehicles equipped with Class II, III, or IV receivers. At just 0.33 lbs and measuring 4 × 2.85 × 8.8 inches, the connector mounts flush to the vehicle's rear electrical harness and presents a clean, weather-sealed installation. The secure snap-latch mechanism prevents accidental disconnection during transit while remaining accessible for quick detach when unhooking the trailer.

This connector serves truck owners, fleet operators, and recreational towing enthusiasts who depend on precise trailer lighting control for highway safety and legal compliance. Whether managing utility trailers, boat haulers, RV setups, or commercial cargo applications, the vehicle-side connector interface is essential for establishing the electrical pathway required by DOT lighting regulations. CURT Manufacturing's proven reliability in the aftermarket towing market makes this seven-pin socket a trusted upgrade for factory or replacement harness installations.

Available as an individual unit, the 58151 integrates seamlessly into existing wiring systems or serves as a standalone vehicle-end connector replacement when original equipment fails or requires upgrading. Pairing this socket with a compatible seven-pin trailer plug completes a secure, code-compliant electrical connection for any trailer towing scenario.
