Universal K-Series Swap Conversion Harness

The Essential Hybrid Racing Universal K-series Swap Conversion Wiring Harness Special Discount [BiKrGAuz] is the ultimate solution for enthusiasts looking to install a K-Series engine into a non-Honda chassis or where a standard plug and play harness is unavailable. This versatile harness is designed for vehicles like Preludes, DA Integras, Accords, and older Honda chassis, as well as custom open wheel cars, Mini Coopers, Toyota MR-2s, Lotus Elises, and full race cars. With over a decade of experience in K-Series swap wiring, Hybrid Racing offers the most widely used and reliable harness on the market.

Comprehensive Harness Features

The race harness includes essential components such as a fuel pump relay, main relay, and primary oxygen sensor relay. It comes pre-wired for the OEM K-Series 02-04 Wideband O2 sensor and features an OBD2 port. Key outputs include a tachometer, speedometer, low oil pressure warning, malfunction indicator, fan control, fuel pump control, and starter relay. To ensure seamless integration, the harness interfaces with your factory dash harness, OEM K-Series engine harness, and K-Series ECU, providing a straightforward plug and play experience. This harness is compatible with all USDM / JDM 02-04 wiring harnesses, including K20A, K20A2, K20A3, but not with 05-06 or K24 engine harnesses and ECUs.

Practical Uses and Benefits

The Essential Hybrid Racing Universal K-series Swap Conversion Wiring Harness Special Discount [BiKrGAuz] is perfect for anyone planning a K-Series engine installation, especially those who prefer using the OEM K-Series ECU. Its broad compatibility and comprehensive features make it ideal for a variety of applications, from street vehicles to race cars. With full tech support and a commitment to quality, Hybrid Racing ensures a trouble-free installation. All wires are labeled and neatly packaged, and the harness is constructed with brand new connectors, terminals, and wire sourced from the same company that Honda uses. This not only guarantees a perfect fit but also minimizes the risk of errors. If you encounter any issues with your swap, Hybrid Racing's expert team is just a call away, providing the support you need to get your project back on track.
