Classic Update Kit - 1973-79 Ford Truck & 1978-79 Ford Bronco

American Autowire Classic Update Kit 510342 – 1973-79 Ford Truck & 1978-79 Ford Bronco

Updating the wiring is an important part of many vintage Ford truck and Bronco builds. The American Autowire Classic Update Kit 510342 provides a modern electrical foundation for 1973-1979 Ford trucks and 1978-1979 Ford Broncos.

The kit is designed for projects that need more electrical capacity and flexibility than the original wiring system provided. It includes the main wiring needed to connect the vehicle from the front lighting and engine area through the rear body, along with provisions for common modifications such as electronic fuel injection, aftermarket gauges, and upgraded charging systems.

The extended harness leads also give builders additional flexibility when routing wiring around custom engine, transmission, and accessory configurations.
