CURT Trailer Wiring Connector (MPN: 55774)

Efficiently connect your vehicle to trailers with ease and reliability.

The CURT trailer wiring connector is designed for USCAR equipped vehicles with factory tow plugs, providing a seamless connection for towing applications. This custom wiring connector, also known as a T-connector, simplifies the installation process with its plug-and-play design, eliminating the need for cutting, splicing, or soldering. It connects directly to the OEM connector, offering both a 4-way flat and a 7-way RV blade socket for versatile towing capabilities.

This wiring connector is particularly beneficial for vehicles that are not pre-equipped with a towing package, as it utilizes a special socket integrated into the vehicle's electrical system. The 4-way flat output is suitable for connecting tail lights, brake lights, and turn signals, while the 7-way round socket accommodates additional features such as reverse lights, electric brakes, and auxiliary power. The included slit loom ensures that wires are contained and protected, enhancing durability and safety.

Installation is straightforward, typically requiring about one hour, and the metal bracket securely mounts the wiring to the vehicle or trailer hitch. This CURT connector is a reliable solution for those looking to enhance their vehicle's towing capabilities without the complexities of traditional wiring methods.
