FT550 Rotax 300 Harness — 4ft / I already have a FT550 ECU / w/ SparkPRO-3 (Nautica / Off-Road) waterproof igniter

The FT550 Rotax 300 Harness 2010-2023 ADAPTER HARNESS, designed by FuelTech, is the perfect solution for FuelTech ECU installation using the PWC OEM harness.

The FT wiring harness has all necessary components for easy and fast FT550 ECU installation.

This wiring harness plugs directly to the OEM harness. There are also two spare extra connectors for inputs and output available in FT550.

Important Note: The OEM Sea Doo IBR (reverse bucket control) and OEM dashboard integration by CAN bus is partially implemented and is not compatible with all year and models, please consult with tech support for updates. Currently only 2022 Sea Doo RXP-X 300 is confirmed to be functional.

The FT550 ECU is not included, purchased separately.
Download and update your FuelTech FT550 ECU with the FT Manager 5.0 or newer version to have the new PWC control features and Base Start Map files of each model.

Versions:
4ft long is recommended for shorter ECU wiring routing, typically for the RXP hulls.
8ft long is recommended for longer ECU wiring routing, typically for the RXT, GTX and similar hulls.
