CURT 56375 Vehicle-Side Custom 4-Pin Trailer Wiring Harness
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 Chevy Equinox (factory tow package required; 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.
To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it..
