Fits 1966–77 Bronco.

This kit has everything you need to modernize your classic vehicle. Kit includes:
  • a new, compact ATO-style fuse box assembly
  • replacement headlight switch with internal 25-amp circuit breaker, adjustable-length shaft, and custom knob
  • new ignition switch with indexed connector
  • standard turn signal flasher, hazard flasher and horn relay mounted on harness
  • original switch connector bodies
  • steering column connectors that will plug directly into most aftermarket steering columns or stock 1966–77 Fords using the adapter and terminals included in the kit
  • instrument cluster wiring designed with a “cluster harness disconnect” for easy service and assembly

All original terminals and connectors are also supplied for original cluster gauges. With the disconnect system, any aftermarket gauge cluster package can be easily and neatly wired in. Flexibility in harness design allows for original or custom routing. Front lighting includes extra-long leads when that custom under-hood appearance is desired.

All light terminals, connectors, and sockets are provided as well as a switch trigger wire for electric fan relay. Engine wiring includes connectors for coil, tachometer, water temperature, oil pressure, electric choke, and electric speedometer, if needed. A heavy-gauge alternator feed and fusible link are also included for any typical high-output 1-wire or internally-regulated alternator. Also includes connectors for H.E.I distributors.

Separate under-dash courtesy light assemblies are also included for use with your original dome / interior light feeds. New dimmer switch is provided. License plate lamp lead connection and fuel tank lead connection are also included.
