Rywire Mil-Spec Universal Race Fuse/Relay Box V3 - For B/D/H-Series Engine Harnesses (V3-SUB-RACE)

Rywire V3-SUB-RACE is a mil-spec fuse and relay box that lets a Rywire B-series, D-series or H-series engine harness run in any car: race cars running the engine only, off-road cars, sand rails, buggies, gutted circuit cars and drag cars. It carries five relays and fuses and has a 4-pin DTP connector for the fuel pump, fan, spare and switched outputs. Run power to the fan and fuel pump, connect the ignition switch and start it up.

Frequently Asked Questions

Will it work with my K-series harness?

Not as-is. It is designed for Rywire B, D and H-series engine harnesses, not K-series or 13B harnesses. Ask us about other Rywire harnesses; adjustments can be made.

Can I use it with a non-Rywire harness?

Yes. It can be supplied with the engine harness pinout and connector mate so integrating it into another harness is straightforward. Email service@tunedbyshawn.com with your engine, chassis and ECU before ordering if you are unsure which configuration you need.
