Description

Classic Update kits provide more circuits than original chassis harnesses, rewiring a vehicle from headlight to tail light. They accommodate add-ons like EFI and aftermarket gauges, featuring an updated ATC fuse panel, modern GXL wire (labeled every 3-5 inches), a pre-built dash harness, and a gauge cluster disconnect. Engine and front light harnesses have extra-long leads for custom routing and updated engine/transmission combos. Includes a six-way power accessory plug, extra-long rear body wiring, a 175 amp mega fuse kit with 6 gauge charge cable for high output charging, original-replacement connectors, terminals, lamp sockets, a headlight switch with a 26 amp internal circuit breaker, a new floor dimmer switch, a steering column adapter kit, a replacement ignition switch (compatible with HEI and EFI swaps), and a new wiper switch. Designed for modified Broncos, not compatible with factory ammeters or stock radio speaker locations. Fuse panel mounts in the glove box; a new glove box liner is required.
