Overnight success for electrical wizard – after 40 years of toil

blackbox-cutoutAt last year’s SEMA exhibition, in early November, the Chester, Pennsylvania electrical firm Ron Francis Wiring suddenly became the authority when it won the New Street Rod Product of the Year award for the striking innovation displayed in their new Blackbox relay system.

Says company head Scott Bowers, “It greatly simplifies complex wiring, particularly in systems with numerous relays.” In fact, the Black box is not just limited to Street Rods, but serves equally well all hot rods, Muscle cars, race cars and others. Used for controlling power windows, door locks, fuel and water pumps and fans, this fully programmable apparatus controls 10 individual relayed circuits and costs $299.95.


Ron Francis UV-resistant flexible braided wire covering. Prepared in 10ft or 50ft lengths, it closes around the wire with a 30 percent overlap, allowing it to easily embrace inline plugs, connectors and splices.

Four quick tips from Ron Francis Wiring

1) Mini fuses are better than ATO-ATC blade fuses because they have silver contacts that prevent them from adhering to the similar metal used in the fuse box. Introduced in 1992, they are widely available, including your local grocery store.

2) Do not solder unless you are experienced. If the solder wicks up the wire strands further than the connector itself, the strand wire becomes solid and can break under vibration. This is why solid core wire in not used on cars.

3) Always use a crash relay. It will immobilize the electric fuel pump in a collision. Fuel injection systems, carburetors, and broken fuel lines can discharge volatile gasoline in seconds, either onto the ground or in the car.

4) Remember, the nomenclature for wire gauges runs in reverse to common logic: the bigger the number, the smaller the wire; the smaller the number, the bigger the wire.
