Installing J's fan switch
This is a very easy mod, one I did last November. J's racing makes a good product.
1) Jack up the front end of the car, putting it on jackstands. This will allow you to see what your working on.
2) Remove the lower front cover (splash shield). This will allow you to see the bottom of your radiator.
3) Locate the stock fan switch. It is on the drivers side of the radiator along the bottom, and looks similar to the J's racing one. Unplug it.
4) Use a wrench to loosen the switch. DO NOT pull it all the way out yet.
5) With the new fan switch in reach, use one hand to take the old switch out. As you do that, coolant with come out of the hole. Use a finger from your other hand to plug the hole. Put the old switch down, and pick up the new one. Remove the finger plugging the hole and screw the new switch in. Use caution and DO NOT over tighten this switch. You can shread the O-Ring gasket easily.
6) Plug it in and you are ready to go.
Some people say you can do this mod by working from the top side of the car, and omit removing that shield. It is a long reach, and your legs will rub against your bumper the whole time. Plus, any coolant that leaks will be trapped on that shield.
Some people also suggest putting some gasket maker on the threads of the switch to prevent a leak. I did not do this, and mine has not once leaked.
Good luck!

Plugging the hole, that the fan switch goes in, with your finger eliminates you having to drain the coolant. You can, but it isn't necessary.
Most of the coolant will drain out of the fan switch hole. I think there is a drain plug in the bottom center of the radiator, or at least there is on my Koyo.
