One of the standout features of this harness is its independent Fuse/Relay box, eliminating the need for any under dash wiring in designated race cars. This streamlined design ensures a clean and efficient setup. Crafted with the utmost precision, the harness features high-quality, temperature-resistant TXL wiring that can withstand the demands of racing environments. 

For EF, EG, EK, DC2 Honda/Acura Chassis, any 02-04 K swap Conversion harness is required for your specific chassis if utilizing the factory under-dash, and ignition. For Universal applications (other chassis) the use of a Universal Conversion harness will be needed. We will provide a C101 Connector adapter that will be plug and play to such conversion harness. For Race car applications with no dash/Interior harness a Switch Panel will be required which is currently in final stages of development.

For added convenience, the harness is equipped with a Milspec Firewall Quick Connect system, enabling effortless removal and installation between the Engine Harness and Chassis Harness. This user-friendly feature saves valuable time and effort during maintenance or modifications.

In addition, our harness provides additional Deutsch connectors, specifically incorporated for expansion in Dual Injector setups, or additional Inputs/Outputs to cater to any additional components that may be essential for your setup. These connectors provide the necessary flexibility to accommodate your specific requirements and eliminates the need to cut into existing harness for add-ons. 

When it comes to versatility, this harness design stands unmatched in the industry. Every connector is conveniently labeled, ensuring effortless installation and eliminating any guesswork. Say goodbye to the hassle of deciphering complex wiring diagrams—this harness makes the installation process a breeze.

By leveraging the factory connectors, this harness offers a plug-and-play solution, allowing for straightforward installation without the hassle of modifying or adapting your current sensor configuration. This not only simplifies the installation process but also ensures compatibility with the original sensors designed for your Honda K20/K24 engine.
