Erik specialises in building top-level motorsport wiring harnesses, choosing to focus primarily on the demanding offroad racing market — but wiring wasn’t always on the cards for this Californian. Despite growing up around hotrods and motorsport with a father who built cars for a living, he was actively discouraged in following his Dad’s footsteps, instead being pushed towards a more conventional career.

The problem was, you can’t really expect your kid to not become a diehard car guy when he spends all his time messing around in your shop full of cool builds and weekend after weekend at the track. So, straight after school, Erik walked into an apprenticeship at a hotrod shop and began building his skills in fabrication, engine building, and nearly everything else in the car building world — but it was wiring that he excelled at. Many years later, Erik is a self-taught maestro building ultra-high-end motorsport looms for some of the most impressive race cars and trucks out there.

In this episode, we dig deep into Erik’s huge bank of knowledge and experience, discussing a big range of wiring-related topics — from the art of concentric twisting, autosport connectors, which tools are worth the investment, the correct gauge of wire to use for different applications, and a whole lot more.

Erik also weighs in on the myth of “Milspec”, discusses the many cases in which a pro motorsport wiring harness is complete overkill, and the lessons learned from running his own wiring business — particularly when it comes to the challenge of accurately quoting work and turning down jobs that you know just aren’t right for you.
