Fan ..... manual switch ('99 450S Foreman)

Wish to install a manual on/off fan switch ..... some say 'blue' wire, while others say 'green' wire. Ideas welcome, thanks.

got a 12 volt dc test light ?..see which wire is hot with key off ?..i highly doubt any will be hot with key off ???..you may need to run straight from battery to fan..green for ground...blue for hot...just install a rocker switch inline on the blue wire...think about a inline fuse as well. the fans are controled by the oil temp sensor..when they get hot ( from oil getting to hot )..they turn fan on..which means...they short to ground..turning the fan on. this only should work when key is on ??...sooo..run wires from battery as i said. not sure how this will effect your oil temp light ?..as it's wired to the fan also. i can say..blue will be hot..green ground...may only work with key on ?.

If you are going to run the fan with a toggle switch right from the battery, that is not good -- switch could be left on and run the battery down.

You need to ground the wire that goes to the temp sensor.

I have a Rubicon. It is White. It has big tires. I like my Can-am better.....when it works.

Sorry for not explaining better ...... I want a manual override on the fan. The automatic switching for the fan works. It's just nice to flip the fan on for 'cool-down' before shut down, and it's nice to flip the fan on before the oil temp climbs too high (as with pulling heavy loads)

My '91 350D has had a switch since almost new, and it was the blue wire then, with the oil temp light coming on when the switch is flipped on.
Just didn't know if it would still be the blue wire now.

There was a video somewhere with the green wire used ..... am unable to find it.

Just wire one side of the toggle to the temp sensor -- then the other side of the toggle switch to ground.

Thank you for the ideas. When the temp sensor is grounded, the fan doesn't come on. Normal?

Did you leave the temp sensor connected as was and attach the toggle to the sensor? Yes use the blue wire that is on the sensor but leave it connected just cut into the blue wire.
