Show original supplier description
The Hybrid Racing K-Series swap conversion harness provides a reliable, plug-and-play wiring solution for installing a K-series engine into a 1999-2000 Honda Civic. By interfacing with the factory dash harness, the OEM K-series engine harness, and the K-series ECU, this unit simplifies the swap process while retaining full functionality of the factory gauge cluster. Each harness is machine-assembled and human-checked, utilizing brand-new connectors, terminals, and wiring sourced from the same manufacturer used by Honda, ensuring quality without the need for soldered joints. This harness is compatible with USDM and JDM 02-04 K-series engine wiring harnesses, specifically including the K20A, K20A2, and K20A3. Note that this product is not compatible with 05-06 or K24 engine wiring harnesses and ECUs. Furthermore, 1999-2000 Civic models originally equipped with the D16y5 engine (typically found in HX trims) are excluded and must use the 96-98 conversion harness instead. European customers utilizing UKDM K20A/K20A2 wiring must adapt the wideband O2 sensor configuration to a narrowband type.
