GM Wiring Harness Systems for Customized Vehicles
(complete head light -to- tail light system)

Our Custom Update Series™ wiring systems are designed with the foresight and engineering to bring your electrical system up to date. They allow you the freedom and flexibility to wire your vehicle the way you want. This system is not a generic wiring harness, but is designed for specific GM models. These wiring systems are popular with owners of fully-customized, pro-street, and retro-rod/modernized vehicles. They require the installer to trim the wires to their desired length, and affix some terminals and connectors to suite their vehicle’s electrical devices. Includes detailed instructions.
