you should read the FAQ for FC sticky thread, it has a whole bunch of stuff on E-fans and yes you will need a thermo-switch, relay and fuse or circuit breaker. If you don't understand them, you should be sticking with the (better than anything aftermarket) stock fan.

Why do you actually want to do this?

NZConvertible : I'm new here, so I'm not wishing to rock the boat. But it's quite feasable to run a e-fan with the stock fc thermo switch. Atleast with an 89 jap import
Used the switch (back of water pump housing/neck) as a negative switching device. to trigger a E-fan through a relay. Works perfectly.

well how come my fan infront of my radiator.. ( behind bumber ) will turn on when that thermo wire is not pluged in.. but then when it is pluged in it doesnt turn on till heat temps get high? i am willing to learn this iwas actually taking time to understand it and i know how to install all the stuff.. just need a thermo switch to get it to work... so there is nothing i can use on the factory motor to get it to work? * i am willing to spend the money just would not like to.. * lol i guess i would never like to spend money but hey.
so can i get this thermo - switch instock at a Shucks or do i need to special order one for my specific vehicle?

iceblue : Did I say something wrong?
My setup is wired.
85 - thermo switch (refering to the single spade(?) terminal switch on waterpump housing in an s5 turbo)
30 - 12v
86 - Ignition source
87 - Fan

Of course when the E fan is on, on these cars without upgraded alts and the volts are dropping under 13.5, then the spark is weaker and power is down with emissions up anyway.

+ 20F is pretty sizeable temp range.

I don't know what fan you have so I'm not saying it WILL be less efficient but it IS a strong possibility. The stock shroud and clutch fan work very well and unless they are broken I would reconsider what you are attempting.

The biggest bitch about installing a thermo Fan was since I've removed the stock shroud I don't have that handy place to put my tools anymore.

Furthermore, due to the fact that an e-fan is either on/off or very discretely stepped, it provides a less stable temperature than the clutch fan, whose viscous lockup is proportional to the heat of the system.
Also, it is not an inexpensive task, since it requires a better alternator, a fan controller and, obviously, the e-fan.
Therefore, unless you either require the engine room for some reason or are unable to use and unable to replace your stock fan, the e-fan is not an upgrade.
