Pro Series Wiring Harnesses From Painless Performance

The guys at Painless Performance literally saved hot rodding in 1990 when they came out with their first hot rod wiring kit, taking those horrible old electrical bird’s nests and simplifying them so rodders could spend hours instead of weeks wiring their cars. Twenty-eight years after Dennis Overholser sold the first wiring kit at the Pate swap meet in Texas – the company and their easy-to-use products have never been more popular.
