The FuelTech FT550 Sea-Doo 325 Plug-and-Play Harness (2002112825) is the adapter harness for installing a FuelTech FT550 ECU in a 2024 and newer Sea-Doo 325 using the PWC's OEM harness — and unlike a universal install, it keeps the OEM gauge cluster and the iBR (Intelligent Brake and Reverse) system working properly.
Key Features
True plug-and-play: all connections needed to install the FT550 quickly and easily on the OEM harness
Retains the OEM gauge cluster and iBR, properly working
Two spare connectors for extra FT550 inputs and outputs — add sensors and actuators later
Or build the complete package: add an FT550 or FT550LITE ECU, an ignition module and the NanoPRO with the options above
Fitment
Sea-Doo 325 models, 2024 and newer (RXP-X 325, RXT-X 325 and GTX 325)
Works with the FuelTech FT550 and FT550LITE ECUs
Requirements from FuelTech: this harness requires the FuelTech NanoPRO to read and condition the stock Bosch LSU 4.9 O2 sensor. The stock 325 coils require an external igniter — either the OEM 3-channel igniter or the higher-energy FuelTech SparkPRO-3 Marine.
