The FT550 2024+ Rotax 325 Harness, designed by FuelTech, is the perfect solution for FuelTech FT550 ECU installation using the PWC OEM harness.

The wiring harness adapter has all connections to quickly and easily install the FT550 ECU, while retaining OEM gauge cluster, IBR (Intelligent Brake and Reverse system) properly working.

This wiring harness plugs directly to the OEM harness. There are also two spare extra connectors for inputs and output available in FT550 if you want to install additional sensors and actuators.

It does require the NanoPRO to read and condition the existing stock Bosch LSU 4.9 O2 sensor.

The stock 325 coils requires an external igniter that can be either a OEM 3 channel igniter we offer or an upgraded energy version that will increase spark energy, the FuelTech SparkPRO-3 Marine version.

The FT550 ECU, NanoPRO o2 conditioner and ignition module are not included, purchased separately.
