This standalone harness is designed for the Honda K20/K24 series engines and is compatible with various setups, including all Honda/Acura chassis, rear-wheel-drive (RWD) conversions, and front-mounted engine swaps. Two versions are available to accommodate different configurations, including an extended interior harness tailored for mid-engine swaps like the Toyota MR2 and Acura NSX.

Key Features:

• Independent Fuse/Relay Box: The harness includes a built-in mini fuse/relay box, eliminating the need for under-dash wiring in race car applications. This design provides a streamlined, clean setup for professional builds.
• Durable Construction: Manufactured with high-quality, temperature-resistant TXL wiring to withstand the demands of racing environments.
• Plug-and-Play Compatibility: Comes with a C101 connector adapter for seamless integration with 02-04 K-swap conversion harnesses (for EF, EG, EK, and DC2 chassis) or universal conversion harnesses for non-Honda chassis.
• Deutsch Connectors: Enables easy expansion for dual injectors or additional inputs/outputs without altering the existing harness, maintaining a clean and adaptable design.
• Clear Labeling: Every connector is clearly labeled for straightforward installation, eliminating the need for wiring diagrams.

Application Notes:

• A charge harness must be run separately (not included).
• High-impedance injectors are required; the harness is incompatible with resistor boxes.
• For race car setups with no interior harness or dash, a switch panel (currently in development) is necessary.

Compatibility:

• Chassis: Suitable for EF, EG, EK, DC2, and other universal setups.
• Engine Sensors: Works seamlessly with factory sensors, requiring no modifications or replacements.
