Rywire Budget Tucked K-Series Engine Harness V2 - K24 Swap (K24-Base)

Rywire K24-Base is the budget Version 2 tucked engine harness for K24 K-swaps. It shares the layout of the K2 mil-spec harness but uses automotive wire in a single black color and expandable loom to keep the cost down, and it carries the K24-style gray crank sensor plug and small K24 knock sensor plug. 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 K24 Swap Harness for Your K-Swap

Rywire K24-Base is a budget tucked K24 swap harness for K-swaps into older Honda chassis: all-new wire, pins and plugs with the K24-style gray crank and small knock sensor plugs, routed like the OEM K-series harness.

• Versus re-pinning your donor harness: Donor K-series harnesses are often 20+ years old, cut, brittle or missing plugs. This Rywire K24 budget harness is built new to order, so no core is needed.
• Versus a universal flying-lead harness: With flying leads you terminate every connector yourself. This Rywire K24 budget harness is crimped with pneumatic heads, ID-labeled, and tested pin to pin and resistance checked before shipping.
• Versus Rywire's mil-spec line (k24-milspec): The Rywire k24-milspec K24 harness has the same V2 layout and connectors, built with Tefzel wire rated to 200 C in factory colors under Raychem DR-25, for a show-quality bay.
• Why pick the budget build: This Rywire K24 budget harness gives the same plug-in fit for less money, using single black wire in expandable loom. Choose it when function matters more than wire colors.
• Version 2 routing: This Rywire K24 budget harness runs through the center or right of the firewall like the OEM K-series harness, works in LHD and RHD cars 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: K24 swaps on a budget that still want a new, tucked, tested harness. K20 engine: Rywire K2-Base. Pair it with a K-Series Chassis Adapter.

Frequently Asked Questions

What is the difference between the budget and mil-spec K-series harnesses?

The connector list and routing are nearly identical. The budget harness uses a different wire in a single black color with expandable loom and white labels; the mil-spec harness uses Tefzel wire in factory colors under Raychem DR-25 with yellow labels.

Do I need a core or a chassis adapter?

No core is needed. You do need a K-Series Chassis Adapter for your chassis, since the harness ends at OEM-style computer plugs A and B.

How are the cam sensors wired?

Rywire wires the TDC plug on the intake side and the CPS plug on the exhaust side: the exhaust cam sensor is the timing reference and the intake sensor references VTC position. The two plugs are identical and sit next to each other, so if you prefer them the other way, swap wires A25 and A26 at the computer plug and reverse the plugs.

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.

Should I buy the Rywire budget or mil-spec tucked K24 harness?

Both use the same Version 2 layout and connectors. The budget K24-Base costs less and uses single black wire in expandable loom; the mil-spec k24-milspec uses Tefzel wire in factory colors under Raychem DR-25 with adhesive-lined junctions.
