American Autowire Classic Update Wiring Harness Kit, 1978-79 Ford Bronco & 1973-79 Ford Truck

American Autowire Classic Update Wiring Harness Kit

This American Autowire Classic Update Wiring Harness Kit is designed for restoration and custom vehicle projects that require more electrical circuits and modern wiring capability than the original factory harness. The system rewires the vehicle from headlight to tail light while supporting common upgrades including electronic fuel injection, aftermarket gauges, updated charging systems, and drivetrain modifications.

Built with modern GXL wiring and an updated ATC fuse panel, the harness features clearly labeled wiring, extra-long leads for custom routing, and factory-style connectors for simplified installation. The kit is designed to support both stock restorations and modified applications with improved electrical reliability and expandability.
