Description

Classic Update kits are designed for projects requiring more circuits than original chassis harnesses. This complete wiring harness rewires a vehicle from headlight to tail light, accommodating popular add-on items like EFI, aftermarket gauges, and other modifications. Features include an updated ATC fuse panel with modern GXL wire (labeled every 3-5 inches), a pre-built dash harness with a gauge cluster disconnect, engine and front light harness with extra-long leads for custom routing, original-style bulkhead connectors, a six-way power accessory plug, rear body wiring with extra-long leads, a 175 amp mega fuse kit with a 6 gauge charge cable for high-output charging systems, original-replacement connectors, terminals, lamp sockets, headlight switch with 26 amp internal circuit breaker, new floor dimmer switch, a dash harness connector for 69+ GM steering columns (with mating connector/terminals for late model columns), and a gauge cluster printed circuit board connector/terminals. The 1968 model year ignition switch connector body must be reused if required; ignition switch connectors for 1969-72 applications are included.
