Has anyone put a switch in line to their electric fan? I want to be able to turn it off for water crossings, so it doesn't break. I was wheeling with a friend who had his fan turn on in water and the plastic fan broke off. If anyone has, which wire did you put the switch on?

Slickwill had one on his late jeep.

Yup, I did. You need a pretty high amp relay (40A+) that's 'normally closed' and then use it on the fan's ground wire. It's a dual speed fan, so it has two power wires. You could always use two relays, one for each hot wire, but it's easier to use a single relay on the ground. You should also consider a waterproof model.

I personally unplug my fan at the connector right near the air box. I don't do water crossings every often, but it is cheaper and easier than a relay install.

Which is the ground? I want to put it on the vehicle side of the plug, so I can take the fan out to clean the radiator.

That is what happened to my buddy when he hit a water hole. That is why I want to do this. I'm getting the relay tomorrow and already have the switch in. I will post some pics when I get it done.
