Rywire Budget Tucked K-Series Engine Harness - K24Z3 Swap (K24Z3-Base)

Rywire K24Z3-Base is a budget tucked engine harness for K24Z3 K-swaps. It uses the newer K24Z3 engine plugs while keeping the popular 2002-2004 RSX computer plugs, so it works with plug-and-play solutions like the Hondata K-Pro and Link/AEM series 2 computers. It follows the OEM K-series layout and connects to your chassis through a K-series computer adapter. Built to order by Rywire in the USA.

Why This K24Z3 Swap Harness for Your K-Swap

Rywire K24Z3-Base is a budget tucked K24Z3 swap harness that plugs into the K24Z3 sensors and coils while keeping 2002-2004 RSX computer plugs A and B for plug-and-play K-series computers.

• Versus re-pinning a donor harness: Mixing K24Z3 engine plugs with RSX computer plugs on a used harness means re-pinning and splicing. This Rywire K24Z3 harness is built that way new, so no core is needed.
• Versus a universal flying-lead harness: With flying leads you terminate every connector yourself. This Rywire K24Z3 harness is crimped with pneumatic heads, ID-labeled, and pin-to-pin and resistance tested before it ships.
• Versus Rywire's mil-spec line: Rywire's mil-spec K harnesses (K2-Mil-spec, k24-milspec) add Tefzel and DR-25 but use K20 or 2005-2006 K24 plugs. This Rywire K24Z3 harness is the build with K24Z3 engine plugs.
• K24A2-style crank plug: This Rywire K24Z3 harness uses the K24A2-style crank sensor plug that the RSX-plug K-Pro computer requires, with the rest of the engine side in K24Z3 style.
• Version 2-style routing: This Rywire K24Z3 harness runs like the OEM K-series harness through the center or right of the firewall, fits LHD and RHD chassis and clears aggressive headers.
• 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: K24Z3 swaps running an RSX-plug computer. K20 or earlier K24 plugs: Rywire K2-Base or K24-Base. Pair it with a K-Series Chassis Adapter.

Frequently Asked Questions

Why does it use RSX computer plugs on a K24Z3?

Keeping the 2002-2004 RSX computer plugs lets you run the common plug-and-play K-series computers such as the Hondata K-Pro and Link/AEM series 2, while the engine side plugs into the newer K24Z3 sensors and coils.

Do I need a core or a chassis adapter?

No core is needed. You do need a K-Series Chassis Adapter for your chassis, which also adds the E-plug.

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.

Why buy the Rywire K24Z3 harness instead of a standard K24 swap harness?

The Rywire K24Z3-Base uses K24Z3-style coil, cam, TDC, injector, knock and alternator plugs, so it plugs into the K24Z3 engine. It keeps 2002-2004 RSX computer plugs A and B and a K24A2-style crank plug for RSX-plug computers.
