Im installing two used Yamaha Z250TXRB HPDI engines, 2003. I'm using the engine harness that came with them. On the starboard top side of both engines is a temp sensor on the top of the cylinder head. The wires are disconnected and I can't seem to find where they connect to. I would assume they go into the harness somewhere but there is no hook up for them, there doesn't appear to be any hook up in the engine either. Does anyone know where these two wires go, or does anyone have a wiring diagram they could share?

Re: Yamaha Z250TXRB temp sensor wire question

Found out it is called a thermosensor assembly. The actual temp sensor is roughly in the same area but lower and works fine. I tested it by grounding it out. Can anyone give me any info on this thermosensor?
