Rywire Honda K-Series (w/FuelTech 550 ECU) Engine Harness w/Chassis Specific Adapter

Rywire is well-known for creating high-quality wiring solutions for performance Honda builds. This engine harness is specifically made for Honda K-Series engines when paired with a FuelTech 550 ECU, and it includes a chassis-specific adapter for a cleaner installation. If you're building a K-swapped vehicle or upgrading your existing K-series setup to run a FuelTech system, this harness is designed to simplify the process and ensure reliable connections.

This harness is built with durable materials and attention to detail, which is typical of Rywire's approach to engine management components. It's designed to integrate seamlessly with both the K-Series engine's factory sensors and the FuelTech 550 ECU, making the wiring process more straightforward than trying to adapt a universal harness. The included chassis adapter means you won't have to cut or splice into your car's original wiring loom, preserving its integrity and making for a more professional-looking install. This is especially important for complex builds where reliability and ease of maintenance are key.

When installing this harness, you'll find that the connectors are clearly labeled and designed to plug directly into their intended locations. This reduces the chance of errors during setup. While this harness is designed for a specific ECU and engine combination, it's a critical component for anyone serious about achieving optimal performance and control from their K-series engine with a FuelTech system.
