Greetings,
Just bought one myself to replace the one I have on a 2004 Utopia 205. Same situation. Sea Doo no longer sells the 2 wire and everyone is saying that the 3 wire should work. According to what I read, it should be the purple/yellow and red/black wires. The website I bought it from suggested "trial and error" meaning trying all combinations to see what works. I was trying to test the one I had with a digital voltmeter and it didn't seem to work. It should produce a voltage when moving the wheel slowly is my understanding. The part number of the old one (on the boat) was 278000970. They sent 278002076 which they claimed it was a direct replacement. There is also 278001998. I'm going to contact the company on Monday. Can you let me know if you get it yours working please. Thanks.
