Rywire - Premium Motorsports Wires, Electronics, & Accessories

Founded and based in Garden Grove, California, Rywire Motorsport Electronics produces high-performance engine harnesses, brake/clutch line kits, PDM switch panels, and drive‑by‑wire components.

Known for their flagship Mil‑Spec, wire‑tucked harnesses, Rywire uses military‑grade Tefzel wiring, Raychem heat‑shrink, and OEM connectors to deliver clean, reliable, and expandable solutions tailored to engine swaps and ECU upgrades.

Their product lineup includes application‑specific harnesses for Hondas (B-, K-, S‑series), Mazdas (RX‑7), Supras, and more, plus support for EV builds and custom installations. Each harness is hand‑assembled in‑house, offering options like charge/ground kits, fuse‑relay sub‑harnesses, and coil‑on‑plug adapters.

Rywire ships dozens of harnesses weekly to builds ranging from drift and drag to show cars and track setups. With a strong DIY and pro support network—including install guides, direct customer service, and active YouTube—Rywire combines engineering precision, motorsport insight, and enthusiast accessibility in every loom.
