FuelTech Sea-Doo Plug-and-Play Harness for FT450/FT550, 2009 & Older 215/255 2002100595

The FuelTech Sea-Doo Plug-and-Play Harness (2002100595) lets you remove the stock Siemens ECU from a 2009 and older Sea-Doo and replace it with a FuelTech FT450 or FT550 standalone ECU — no modifications to your race watercraft, and fully reversible if you ever want to return to stock.

Key Features

• True plug-and-play ECU swap for 2009 and older Sea-Doo 215 and 255 models
• Already running an FT550 on another vehicle? Share the ECU — connect the harness to the ECU's A plug and use the included blank connector on the B plug to protect against water intrusion
• 2 available inputs from the FT450 ECU can be wired from the EXTRA connector to additional sensors (fuel pressure, oil pressure, tunnel pressure, temperature and more)
• 2 available outputs for a boost controller, nitrous, an additional fuel pump and more
• FuelTech CAN bus available for add-ons like the EGT-4 and Nano / NanoPRO wideband O2 conditioners
• Trim control remains functional as stock

What's Included

• 1 × FuelTech Sea-Doo Plug-and-Play Harness (2002100595), with blank B-plug connector
• Or configure the complete package: add an FT450 or FT550 ECU and a 3-channel igniter module with the options above

Fitment

• Sea-Doo 215 and 255 models, 2009 and older
• Works with the FuelTech FT450 and FT550 ECUs

Notes from FuelTech: this harness requires a 3-channel igniter module — the OEM 3-channel igniter or the higher-energy FuelTech SparkPRO-3 Nautica. The stock gauge cluster will no longer be functional, and there is no trim indicator on the dash.
