What Rywire does

Rywire Motorsports Electronics is a privately held U.S. manufacturer, founded in 2010 and based in Garden Grove, California, that designs and builds motorsports-grade engine and chassis wiring harnesses, power distribution modules, and engine-management integration products for the performance and racing aftermarket. Its core technology centers on Mil-Spec Tefzel wire construction rated to 200°C with pneumatic crimping and 100% pin-to-pin quality testing, modular sub-harness architecture that allows a single engine harness to migrate across chassis, and the proprietary Rywire PDM 16 — a solid-state, fuse-less power distribution module with 16 configurable 25A outputs, 200A maximum capacity, 52 CAN inputs, PWM capability, and onboard current-draw data logging. The company supports integration with at least eight aftermarket ECU brands (AEM Infinity, Haltech, Link, Motec, Emtron, FuelTech, Syvecs, Hondata) and resells complementary components such as AEM, AiM, Motec, and Moristech products.

The product portfolio spans tucked engine harnesses for Honda/Acura B-, D-, F-, H-, K-, and L-series engines, Mazda 13B, Nissan SR20DET, Toyota 2JZ, GM LS1/LS3, and Porsche platforms; chassis/body harnesses with integrated switch panels and gauge-cluster CAN support; and the BBI-branded air-cooled Porsche EFI ecosystem, including ITB systems and EFI electronics packages developed in partnership with BBI. Pricing ranges from approximately $25 for simple adapters to $13,500 for complete BBI Porsche ITB systems, with custom Mil-Spec harnesses starting at $3,500.

Rywire sells exclusively direct-to-consumer through its e-commerce website (rywire.com) with phone-based technical consultation, ships globally, and positions itself as a Made-in-the-U.S.A. niche supplier. Customers are primarily individual motorsports enthusiasts, import tuners, and Porsche owners performing engine swaps, alongside professional race teams; revenue is generated through one-time hardware sales with no subscription or recurring contract structure. The company operates with 1–10 employees, has no disclosed outside funding, and reports no management team or institutional ownership in the available data.
