American Autowire Classic Update Kit for 1978-80 Chevy Camaro

The American Autowire Classic Update Kit for the 1978-80 Chevy Camaro is built to fully rewire your vehicle and support extra electrical circuits, such as electronic fuel injection, updated gauges, and other common add-ons. It uses modern GXL wire with printed labels and an ATC fuse panel for better circuit protection and easier troubleshooting. The kit includes a 175-amp Mega fuse and 6-gauge charge cable to safely handle higher-output alternators. Wires are extra long for flexible routing with modern engines or custom installations. The harnesses are designed for direct integration with factory switches and connectors while also supporting common aftermarket parts, such as steering columns and instrument clusters. Every component is carefully selected for its durability and technical performance, featuring detailed routing, factory-style connectors, and robust fusing.

The headlight switch shaft may require trimming, as noted in the instructions. Use proper crimp and solder tools for each electrical connection. Grease and seal exterior connectors to prevent corrosion. Reconnect the battery only after securing the ground between the battery, engine, and frame.
