American Autowire 60-66 Chevy/GMC Truck Classic Update Kit (AAW500560)

The American Autowire 60-66 Chevy/GMC Truck Classic Update Kit (AAW500560) is a comprehensive wiring solution designed to completely replace the electrical system in your 1960-1966 Chevrolet or GMC truck. This kit is ideal for restoration projects that require more circuits than the original chassis harness provided, allowing you to seamlessly integrate modern components and popular add-on items like electronic fuel injection, aftermarket gauges, and modern air conditioning systems. The harness is built with high-quality, modern materials and is specifically engineered to fit the original vehicle’s chassis, ensuring a professional and clean installation.

KEY FEATURES AND BENEFITS:

• Accommodates Modern Accessories: The kit provides the necessary circuits and connectors to support popular modifications, including electronic fuel injection (EFI) systems, aftermarket gauges, and modern charging systems.
• Simplified Installation: All GXL (automotive-grade) wires are clearly labeled every 3 to 5 inches, which significantly reduces installation time and helps prevent wiring errors.
• Extra-Long Leads for Customization: The engine, front light, and rear body harnesses feature extra-long leads, providing you with the flexibility to route wires exactly as you need for a custom look or to accommodate a unique engine or transmission setup.
• Updated Safety and Reliability: The kit includes a modern ATC (blade-style) fuse panel and a new 26-amp headlight switch with an internal circuit breaker, offering improved safety and reliability over the original glass fuses and components.
• High-Output Charging System Support: A 175-amp mega fuse kit and a 6-gauge charge cable are included to safely support high-output alternators and modern charging systems.
• Vehicle-Specific Design: This is not a generic kit. It comes with original-style bulkhead connectors and a dash harness connector that fits a 1969-and-up GM steering column, ensuring a precise fit.
