• Easy Installation: The FuelTech-designed Seadoo Rotax 300 2010 - 2023 ADAPTER HARNESS is the ultimate solution for hassle-free FuelTech ECU installation using the PWC OEM harness. The FT wiring harness comes with all necessary components for a quick setup. • Direct Plug-in: This wiring harness plugs directly into the OEM harness. The FT550 also offers two spare extra connectors for inputs and outputs, giving you more flexibility. • Multiple Versions: Choose between a 4ft long version for shorter ECU wiring routing (great for RXP hulls) and an 8ft long version for longer routing (ideal for RXT, GTX and similar hulls). Important Note: The OEM Sea Doo IBR (reverse bucket control) and OEM dashboard integration by CAN bus is partially implemented and not compatible with all years and models. Only the 2022 Sea Doo RXP-X 300 is currently confirmed to be functional. Consult tech support for updates. The FT550 ECU is not included and needs to be purchased separately. Download and update your FuelTech FT550 ECU with the FT Manager 5.0 or newer version to access new PWC control features and Base Start Map files of each model.
