The wiring in your classic pick-up is about fifty years old and probably not up to the task anymore. These harnesses plug into many of the original switches and connectors, but include:

  • Modern fuse panel
  • Ignition switch
  • Headlight switch
  • Dimmer switch
  • Connectors for tilt columns
  • Heavy-duty alternator leads
  • Dome lights
  • Head and tail lights, etc.

Everything is color-coded and instructions are included - it's a painless process. For 12 Volt upgrades.
