K-Series ECU Harness

The Hybrid Racing K Swap Conversion Harness provides a simplified wiring process for K-Series engine swaps. This harness ensures the retention of full factory gauge cluster functionality. Constructed with brand-new connectors, terminals, and wiring sourced from the same manufacturer as Honda, each harness is machine-made and human-checked for reliability. It features clearly labeled wires and uses no soldered joints for a clean installation. Compatibility includes USDM and JDM 02-04 K-Series engine harnesses (K20A, K20A2, K20A3), and it uses the factory wideband O2 sensor. Note that European customers with UKDM harnesses may need to convert to narrowband. This harness does NOT work with 05-06 or K24 engine harnesses and ECUs. It is also not compatible with some European market 92-95 Civics equipped with a carburetor. The harness is compatible with 1992-1995 Honda Civic, 1993-1997 Honda Del Sol, and 1994-2001 Acura Integra. It ships fully assembled and ready for installation, often with overnight shipping available, and includes a full replacement warranty and free tech support.
