The Rywire RY-K2-FUELTECH-550-EF is a fully populated race engine harness designed for Honda K-Series engine swaps using the FuelTech 550 ECU in 1988-1991 Honda Civic/CRX (EF chassis) applications. This universal race loom incorporates all essential functionality required for high-performance front-wheel drive Honda builds.

Key Features:

• Designed specifically for FuelTech FT550 and FT600 ECU systems
• Pre-terminated connectors positioned exactly where needed

• AEM intake air temperature and MAP sensor provisions
• Chassis-specific adapter harness included for EF Civic/CRX integration

This harness requires a chassis adapter for proper installation and is compatible with Rywire's standalone RACE fuse box and switch panel systems for a complete plug-and-play solution. Engineered with feedback from world-class front-wheel drive race teams, this harness delivers the flexibility and terminations needed for serious competition builds.
