Classic Technologies proudly presents this aftermarket fuse box that is the perfect choice for rewiring your classic car, hot rod, or kit car. The 15 fuses, 7 relays, and 2 flashers coupled with the internal wiring takes the time, difficulty, and clutter out of rewiring a car properly. Its size was kept to a minimum to allow the most mounting flexibility. It is only 6 3/4" (171mm) long X 4 5/8" (81mm) wide X 2 3/16" (56mm) tall.

There is a short video to the left that highlights the main features of fuse boxes and provides some background information.

For your convenience and budget, Classic Technologies offers different Fuse Box kit buying options.

All kits options come with a poster size color schematic, instruction manual, and various accessories. There is an option for standard thermal flashers or flashers for LED tail lights. There is a Spare Relay in the fuse box that can be preconfigured to be ground or 12V actuated. If the spare relay is for an electric radiator fan, it should be ground actuated. If it is for driving lights, it would be 12V actuated. The default configuration is with thermal flashers and the Spare Relay ground actuated.
