That particular switch is for the operation of the temperatue light and is located on top of the engine head.
The older polaris's ,have the fan switch located in the radiator, either at the top or lower right hand side.
There used to be a switch for a toyota that quite a few people were using, i cannot find the number, maybe someone will chime in and give it.
Thank you, that had me kind of stumped cause I see the electrical schematics, and the fan control is in the radiator. So other than a Head temperate Waring light what does it serve??? Do I need it cause if not... Pssst I'm not buying it, unless a cheep Toyota one does exists!
