Hybrid Racing's Conversion Wiring Harness is a trusted and widely used solution for K-Series swaps in 92-95 Civic, 93-97 Del Sol, and 94-01 Integra models. With over ten years of experience in K-Series swap wiring, this harness powers countless K-Swaps worldwide, ensuring a reliable and efficient connection.

Simplified Plug-and-Play Installation

Designed for ease, the K-Swap harness interfaces seamlessly with your factory dash harness, OEM K-Series engine harness, and K-Series ECU. This plug-and-play approach simplifies the installation process, allowing for straightforward integration without the need for complex wiring modifications.

Preserves Factory Gauge Cluster Functionality

Hybrid Racing's Conversion Harness guarantees full functionality of your vehicle's factory gauge cluster and comes with a comprehensive replacement warranty. Unlike other options that require sending in parts of your stock harness, Hybrid Racing's harnesses are ready to ship without the need for a core, available for overnight delivery.

Broad Compatibility with Engine Harnesses

The harness is compatible with all USDM/JDM 02-04 wiring harnesses, including K20A, K20A2, and K20A3. It is designed to use the factory wideband O2 sensor. European customers using UKDM K20A/K20A2 wiring harnesses will need a conversion for narrowband sensor compatibility. Note that this harness is not compatible with 05-06 or K24 engine wiring harnesses and ECUs, nor with certain European market 92-95 Civics with carburetors.

High-Quality Connectors for Error-Free Installation

Hybrid Racing employs brand new connectors, terminals, and wires from the same supplier as Honda, ensuring the highest quality and consistency. These components, sourced from Japan, minimize potential errors as no soldering is involved. Each harness is machine-made and checked by humans to ensure it is free from issues.

Comprehensive Technical Support for Your Project

Every Hybrid Racing harness comes with full technical support. This includes assistance beyond the harness itself, encompassing any aspect of your swap. Hybrid Racing provides expert guidance, akin to having a knowledgeable friend who has completed numerous K-Swaps.
