CURT Trailer Wiring Connector (MPN: 55664)

Efficient plug-and-play solution for vehicle-to-trailer wiring.

The CURT trailer wiring connector is designed to simplify the process of connecting your vehicle to a trailer. This custom wiring connector, also known as a T-connector, allows for a straightforward installation without the need for cutting, splicing, or soldering. It is specifically engineered for USCAR equipped vehicles that come with factory tow plugs, ensuring compatibility and ease of use.

This connector features both a 4-way flat and a 6-way round socket, providing versatile options for connecting tail lights, brake lights, turn signals, and additional functionalities such as electric brakes and auxiliary power. The 4-way flat output is essential for standard trailer lighting, while the 6-way round socket enhances the connection capabilities for more complex towing needs.

The CURT wiring connector is built with durability in mind, featuring a slit loom that keeps wires contained and protected from damage. Additionally, a metal bracket is included to securely mount the wiring to the vehicle or trailer hitch, ensuring stability during use. With an estimated installation time of just one hour, this plug-and-play design makes it an efficient choice for those looking to enhance their towing capabilities.
