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. Original-style bulkhead connectors included.
  • 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.
  • Dash harness connector for the 69+ GM  steering column connector. A mating connector and terminals are included for easy adaption to popular late model columns.
  • Replacement ignition switch that is compatible with HEI and EFI swaps.
  • Gauge cluster printed circuit board connector and terminals included.
