All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular connector provides a 4-way flat socket while retaining use of the existing OEM 7-way. It is designed to be a custom wiring option for a number of specific applications within Buick, Cadillac, Chevrolet, Dodge, Ford, GMC, Hummer, Infiniti, Jeep, Nissan, Ram and Saturn (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). It comes with a dust cover to keep the connector socket clean when not in use and a one-year limited warranty. To ensure long-lasting reliability, the majority of CURT custom wiring connectors are made in the USA, and all are thoroughly tested for optimal functionality.
