Rywire K2 Mil-Spec Engine Harness

Rywire K2 Mil-Spec Engine Harness

You want a tucked K20 or K24 bay that still uses factory wire colors and 02-04 K-Pro style plugs, without buying a pre-configured dealer pack. This is the official Rywire K2-Mil-spec Version 2 base harness (ID K2-Mil-spec). It is not the published RYW-K2-MIL-01-10 configured pack. Rywire routes Version 2 more like an OEM K-series loom through the center or to the right on the firewall, which helps RHD Civic and Integra swaps and still works on LHD. You still need a K-series chassis adapter for the interior E-plug. Rywire harnesses are warrantied and non-refundable, and there is no core.

What It Is and Why It Works

Rywire's K2-Mil-spec Version 2 uses mil-spec Teflon-coated ETFE (Tefzel) wire with factory colors and a 200 C heat rating, loomed in Raychem DR-25 with adhesive-lined junctions. Connectors are pneumatically crimped and tagged with yellow labels. Official connectors include VTEC, VTC, oil pressure, 02-04 K20 crank, coils 1-4, exhaust CPS, intake TDC, 02-04 K20 ECT and knock, IAT, alternator, MAP, TPS, idle control, VSS, injectors 1-4, H2O sender, reverse lights, reverse lockout, starter, computer plugs A and B, power distribution, ground, and two extra wires. Rywire wires TDC on the intake and CPS on the exhaust. You can swap A25 and A26 at the ECU if you want those reversed.

What to Know Before You Buy

Rywire warrantied this harness and will help on the phone, but it is non-refundable. No core. Injector plug type, VSS location, charge harness, quick-disconnect plate, and LHD/RHD are options on the official page and are not assumed on this base SKU. You still need the interior computer adapter for your Civic, Integra, or other chassis. Do not use this as an 05-06 RSX harness. If you want the Hybrid Racing configured pack with extras already selected, that is a different published SKU.
