I was getting an oil/overheating alarm horn intermittently on the lake the other day. Plenty of oli and the motor is using it. No performance issues. If I get it again I'm going to follow the procedures in the manual for checking the alarm sensors- It says to first disconnect blue wires at bullet connectors from the oil sensors and it that doesn't have an effect, to disconnect the tan (or tan/blue wire). I found the connectors of the blue wires easy enough but cannot locate one for the tan ( I don't seem to have a blue/tan) I did find one place on the powerhead that has a tan wire and a bullet connector it that it?

Thanks

Looks like Tan color and if so then yes that should go to the Temp sender
