American Autowire Classic Update Kit - 73-79 F100 / 78-79 Bronco

Classic Update kits are designed for projects that require more circuits than would have been available in an original chassis harness. Each kit includes all the basics needed to rewire a vehicle from headlight to tail light, and will accommodate popular add-on items such as electronic fuel injection, aftermarket gauges and common supporting modifications. This harness includes:

• An updated ATC fuse panel and fuses, along with modern GXL wire throughout. Wire functions are labeled every 3 to 5 inches.
• Pre-built dash harness and our exclusive gauge cluster disconnect system for use with stock or aftermarket instruments.
• Engine and front light harness with extra-long leads for custom routing and updated engine and transmission combinations.
• Six-way power accessory plug can be used as a convenient power source for aftermarket accessories.
• A rear body wiring with extra-long leads for custom routing.
• 175 amp mega fuse kit with 6 gauge charge cable to support a high output charging system and internally regulated alternator.
• Original-replacement connectors, terminals and lamp sockets.¬†
• Headlight switch with 26 amp internal circuit breaker and new floor dimmer switch included.
• Steering column adapter kit can be used to mate with stock or aftermarket columns.
• Replacement ignition switch that is compatible with HEI and EFI swap

Note:

• If the 510342 Classic Update Kit is being purchased for a 1978-79 Ford Bronco, the Power Tailgate Harness 510358 add-on harness must be purchased to complete the installation.
• If the 510342 Classic Update Kit is being purchased for a 1973-79 Ford Truck with dual fuel tanks, the Dual Fuel Tank Harness 510359 add-on harness must be purchased to complete the installation.
