Rywire K-Series Rear Wheel Drive Engine Harness - K20/K24 RWD Swap (K2-RWD)

Rywire K2-RWD is a rear-wheel drive K-series engine harness for K20 and K24 RWD swaps running a 2002-2004 Hondata K-Pro or OEM K20A computer. It is built for both left-hand and right-hand drive cars, with S2000 transmission plugs by default and chassis integration for the Honda S2000, BMW E30 or any race car through flying leads, a Rywire race fuse/relay box or a Rywire PDM system. Built to order by Rywire in the USA.

Why This K20/K24 RWD Swap Harness

Rywire K2-RWD is a K20/K24 RWD swap harness: K-series engine plugs, S2000, CD009 or BMW ZF transmission plugs, and chassis integration for the S2000, BMW E30 or a race car.

• Versus re-pinning a front-drive K-series harness: A donor K-series harness is laid out for a front-drive car and Honda front-drive transmission. This Rywire K-series RWD harness is built for rear-drive packaging, with rear-drive transmission plugs.
• Versus a used junkyard harness: Donor harnesses are often 20+ years old, cut or missing plugs. This Rywire K-series RWD harness is all new, pin-to-pin and resistance tested, and needs no core.
• Versus a universal flying-lead harness: This Rywire K-series RWD harness arrives with every engine plug terminated and yellow ID labels. Flying leads remain an option for the chassis side if you integrate the interior yourself.
• Built for your engine: This Rywire K-series RWD harness is built with K20 or K24 crank and knock sensor plugs, your injector plug, and B-series or K-series TPS and MAP plugs, all chosen at checkout.
• OEM color layout: This Rywire K-series RWD harness uses automotive-grade wire in the OEM color layout, so circuits read directly against factory Honda wiring diagrams. LHD and RHD cars are covered.
• Built by a Honda swap wiring specialist: Rywire built the 1988 CRX K20 featured in Super Street (2009) and the ITR-powered E-AT Civic on the November 2013 Honda Tuning cover.

Best for: Rear-drive K20 or K24 swaps on a 2002-2004 K-Pro or OEM K20A computer. Front-drive Honda chassis: Rywire K2-Mil-spec or K2-Base. Haltech: the Rywire K-series Haltech harnesses.

• Chassis Integration: how the harness connects to the car. S2000 or BMW E30 builds the chassis side for that car; Flying Leads leaves unterminated leads; Mating Connector adds the mating plug; Race Fuse/Relay Box adds the Rywire race box for any chassis; Rywire P14 PDM System is for cars running a P14 PDM purchased separately.
• Transmission, MAP & Crank/Knock Plugs: S2000 (default), CD009 or BMW ZF transmission plugs or flying leads; the MAP sensor plug, B-series (default) or K-series; and K20 or K24 crank and knock sensor plugs to match your engine.

Recommended Add-Ons

Will it work with a K24?

Yes. It is designed for both K20 and K24 engines; choose the K24 crank and knock plugs in the options.

Can Tuned By Shawn help with the rest of the swap?

Yes. Email service@tunedbyshawn.com with your engine, chassis and ECU before ordering if you are unsure which configuration you need. If you would rather run a standalone computer, Rywire also builds the K-Series Haltech harness (K2-Haltech-Elite), and Tuned By Shawn can tune your swap on Haltech.

Can I use a front-wheel-drive K-series swap harness in a rear-wheel-drive car?

A front-drive K-series harness is laid out for a front-drive chassis and transmission. The Rywire K2-RWD is built for rear-drive swaps, with S2000, CD009 or BMW ZF transmission plugs and chassis integration for the S2000, BMW E30 or a race car.
