Show original supplier description
The Hybrid Racing K-Series Swap Conversion Wiring Harness is engineered to simplify the process of swapping a K-Series engine into a 2001-2005 Honda Civic. This harness acts as a crucial link, directly interfacing with your vehicle's factory dash harness, the OEM K-Series engine harness, and your K-Series ECU, enabling a straightforward plug-and-play K-Swap experience. Constructed using brand new connectors, terminals, and wire sourced from the same supplier as Honda, this harness minimizes the chance of errors and ensures reliability. All connections are machine-made and human-checked for quality assurance, with no soldered joints. The wires are clearly labeled and neatly packaged to facilitate a trouble-free installation. This conversion harness is compatible with all USDM/JDM 02-04 wiring harnesses, including those for K20A, K20A2, and K20A3 engines. However, it is important to note that this harness does NOT work with any 05-06 or K24 engine wiring harnesses. European customers using UKDM K20A/K20A2 wiring harnesses will need to convert the harness to use a narrowband sensor, as this harness is wired for the factory wideband O2 sensor. Hybrid Racing also provides comprehensive tech support for any questions or issues related to the swap process.
