All depends on which circuit you choose. You will need a relay, switch, and fuse (or circuit breaker) for sure and possibly a temp sender.

I guess I'll just go the easy route and use the Painless kit from Summit.

that painless stuff is expensive. Try this http://www.jegs.com/i/JEGS/555/10560/10002/-1
or go to jegs.com and search for "fan switch"

I got my setup from the auto parts store (Parts Plus). They have some painless fan relay kits right on the shelf.

Wow, the JEGS stuff is a lot cheaper. Alright, I think I'll just buy that kit. Thanks a bunch.

Why not just wire from sensor (switch) to the battery?
that way the fans run till colling is done.

'Cause if your dumb like me, your fans might come on while you are fidgeting around in the engine bay. 
Seriously though, I never did like the thought of autonomous fans, even though GM did that on some vehicles even early on.
I think the consensus is that each fan motor needs at least a 30 amp relay, but you should go back and see what everyone else has run. My GM fans run fine on 30 amps, but I thought I saw that the Windstar fans drew enough that 30 amp relays might be borderline.

yup, 25 amp breakers for me with 30 amp relays has been fine... it's never tripped...

My lincoln MARK VIII fan draws 45 amps continous at full speed. Burns up 30 amp relays like a matchstick. I bought a progressive speed fan controller (varies speed according to engine temp) to do the job but it is very easy to wire them yourself for on/off control.

I've got some decent Hayden 14" fans from Kragan's and they are rated for 11 amps each. I've run both on a 30 amp relay. Am I running it too close?

Yup, i actually ran a 70 amp relay out of a semi truck while i was waiting for my controller to show up. The controller has dual 30amp relays but can be ordered with dual 60 amps aswell.
Thats ONE fan?? Is that one of the two speed versions that I hear about?

One big fan, some have dual speeds some do not, mine is single speed only.

I'm all set , except I have to figure out how to mount my Windstar fans.... any body got pics of theres???
I just tucked mine under the radiator hold down or whatever its called. I still have to put something on the bottom so it wont flap around, but it is pretty solid in there.
Now for the hijack. What gauge wire are people running with windstar fans?

Would this kit work on Windstar fans ?
Cus ya know theres 2 fans , and I think 1 has 2 speeds...?
But I have heard people say the 1 big one is enough by its self???
Anyone know the real deal?

I dunno, I just purchased the kit for my Windstar fans. I never thought about that, but I'm sure there's a way to modify it slightly to use 2 fans. I guess we'll see when I get it.

i used the Hayden part# 3647 kit to wire my Windstar fans up in my 77....it has a dual purpose relay and adjustable thermostat to run dual fans...cost me about $35...works like a charm..wired up one fan to come on at 195 and off at 170 and the other to come on at 200 and off at 180

I've got that kit plus another one without a thermostat running windstar fans. Jegs sells both. heres a pic of them installed.
mine are wired with two on/off/on rocker switches, one for each fan. On with the temp switch/off/on with ignition on.
