SEMA 2017: Express Race Wiring System From Ron Francis Wiring

One of the most intimidating parts of building a racecar can be the wiring. Generally, when it comes to pre-made harness kits, you either went with a full-blown wiring kit, which ends up leaving you with a bunch of unused circuits, or a basic racing-oriented kit that usually requires a lot more wiring. Ron Francis Wiring realized this and has come up with a solution in their new “Express Series” race wiring kit.

“We’ve taken our Bare Bonz race wiring kit, which is an eight-circuit, eight-fuse race-only kit, and elevated it to the level of our Express kits,” explained Scott Bowers. “Designed for the racer, the Express Race kit is not street-legal, as there are no turn signal flashers or headlight circuits, but it still has 16 fuses. It’s designed for an electronics-heavy racecar, but with all the ancillary stuff deleted.”

Besides eight additional fuses and an additional relay over the Bare Bonz Race kit, the Express Race kit has all the same features as the full-vehicle Express kits – color coded and correctly sized wires, wire descriptions printed every five inches, and a junction box that has all the needed fuses and relays in an easy-to-connect package.

Now, with Ron Francis Wiring’s Express Race wiring kit, everything you need for a non-street-legal vehicle is in a single block, as the 18-circuit/16-fuse/4-relay system effectively bridges the gap between the complete car harnesses with extraneous pre-wired circuits and a basic kit that requires additional circuits to be added. The Express Race wiring kit sits perfectly between “too much” and “not enough.”
