CURT 56364 Vehicle-Side Custom 4-Pin Trailer Wiring Harness (QTY 1)
Manufactured by: Curt
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model Some automotive manufacturers install a special socket on the vehicle to be used 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 Rather than requiring you to cut, splice and solder into your vehicle's wiring system, 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 a 4-way flat All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit.
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 It also comes with a dust cover to keep the connector socket clean when not in use.
