      Description

      Complete Wiring Solution. The Wiring Harness is a comprehensive 21-circuit solution designed to simplify electrical integration in custom and restoration projects. With GM-compatible column connectors and color-coded wires, this harness offers reliable connectivity for everything from headlights and turn signals to ignition and charging systems. Its extended wire lengths make it suitable for a wide variety of universal vehicle applications, with support for both classic and modern builds.

      Construction and Appearance. Engineered with high-quality insulation and clearly labeled, GM color-coded wiring, this harness is built for ease of use and long-lasting performance. It includes vital components such as a horn relay, headlight circuit breaker, alternator plug, and dimmer switch connector. The layout is well-organized and optimized for installation flexibility, even in complex or large-vehicle applications.

      Installation. Installation is considered hard and requires electrical knowledge, planning, and proper tools. Some adaptation and custom routing may be necessary, especially in non-GM vehicles, though the universal design supports a wide range of applications.

      Warranty. This harness comes with a one-year limited warranty for peace of mind and product assurance.

      Application. This Wiring Harness fits a wide range of vehicles with universal fitment, though some adaptation may be required depending on the make and model.
