Product Notice

Our Classic Update Series™ wiring system is designed for an upgraded/modified vehicle. Consequently, it:

  • does not support an ammeter, but will support a voltmeter.
  • does not support a stock generator, voltage regulator, or externally regulated alternator, but will support an internally regulated Delco "SI" Series or 1-wire alternator. Some adapters may be available for use with other internally regulated alternators. Refer to our online catalog.
  • does not connect to factory-original wiring since this complete system will replace all of your original wiring.

This Classic Update Series™ Wiring System is recommended only if you are building a fully customized, mostly customized, retro-mod/retro-rod type of vehicle. It is designed for that purpose. If your goal is to keep your vehicle to its factory-original or primarily factory-original configuration, we highly recommend that you purchase our individual Original Design Series wiring harnesses instead, then make any wiring modifications necessary to accommodate your upgrades/modifications.

All our wiring is Made in America
