This FuelTech FT550 standalone engine harness is designed for Honda K20/K24 series engines and comes with a built-in mini fusebox. Specifically, this version includes an extended interior harness tailored for mid-engine vehicle swaps, such as the Toyota MR2 and Acura NSX, ensuring optimal fitment and ease of installation in rear-engine setups.
A key feature is the harness's independent fuse/relay box, eliminating the need for under-dash wiring in dedicated race cars. This design provides a clean, efficient, and reliable setup. Crafted with high-quality, temperature-resistant TXL wiring, it is built to endure the demanding conditions of motorsport environments.
Compatibility and Requirements:
- For Honda/Acura Chassis (EF, EG, EK, DC2): A 02-04 K-swap conversion harness is required for specific models using factory under-dash and ignition setups.
- For Universal Applications (other chassis): A universal conversion harness is needed.
- A C101 connector adapter is included, ensuring plug-and-play compatibility with conversion harnesses.
- For race cars without a dash or interior harness, a switch panel (currently in development) will be required.
Highlights for Rear-Engine Applications:
This extended harness is optimized for mid-engine swaps, ensuring adequate length and perfect integration in platforms like the MR2 and NSX. Its enhanced flexibility simplifies routing while maintaining a professional and streamlined look.
Additional Features:
- Deutsch Connectors for seamless expansion, supporting dual injectors or additional inputs/outputs. This eliminates the need to modify the existing harness for upgrades.
- Each connector is clearly labeled for straightforward installation without requiring complex wiring diagrams.
- Compatible with factory sensors for a plug-and-play experience, avoiding the need for additional modifications.
