Rywire builds the wiring serious swap builds end up running. Founded by Ry Mandell, the brand is known for tucked engine harnesses, Mil-Spec construction, and the clean-bay hardware that goes with them — custom radiators, hydraulic clutch lines, ground kits, and chassis-specific adapters. Whether you're wiring an RB into an S-chassis, a VQ swap, or a K-series into a Civic, Rywire is the harness most builders wish they'd bought the first time.
Yes. We source Rywire products directly through thier distribution channels. Every harness, radiator, and adapter ships with full Rywire documentation. We've been a JDM and tuner performance specialist since 2004 — if a brand is in our catalog, the supply chain is vetted.
In-stock Rywire products typically ship within 1 to 3 business days. Anything labeled as custom or made to order will have variable ETAs. We confirm lead time at order placement and update you when your harness ships from Rywire.
Rywire custom-built items are made to your specs and are non-returnable once production starts. This is standard across the industry for one-off wiring work. In stock parts are returnable within 30 days if unused. Manufacturer defects are covered directly by Rywire, and we handle the RMA process for you. See our full Returns Policy for details.
Rywire products are made in the United States
