4-Pin CURT Vehicle-Side Custom Trailer Wiring Harness, Fits Select Buick Envision

CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection.

Each one is custom-fitted to work with a specific make and model, built with some of the most advanced technology in the industry.

Some automotive manufacturers install a special socket on the vehicle for vehicle-to-trailer wiring.

Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation.

The custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form of a 4-way flat.

All CURT custom wiring connectors are made vehicle-specific for the best fit and easiest possible installation.

This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Buick Envision (to verify your vehicle compatibility, see application info).

It comes with all necessary hardware to establish a solid connection and includes a dust cover to keep the connector socket clean when not in use.

All CURT custom wiring connectors are thoroughly tested for optimal functionality to ensure long-lasting reliability.
