my elec radiator puller fan instructions say i need to connect my power supply through my fuse box how do i do that? i been lookin' at it after work for two days and im stuck;) HELP i cant live w/out my runner

I just did this but I forgot all the details; nevertheless, I believe I have the answer to your problem.
If I'm not mistaken you are only concerned with the one wire that is supposed to hook up to a positive switch source, right? Everything is dirt simple. You should have your ground, the A/C relay wire, the 10 gauge (heavy duty thick wire) hooked up to the battery (positive +). The wire that you are concerned with does not draw a lot of current, the 10 gauge one that hooks up to the battery (+) does, that's why it uses the in line fuse.
You can hook it up two ways, stay on when the key is off or turn off when key is off. I have mine hooked up to turn off with the key, otherwise the fan will stay on until the engine is cool which is about one minute. If you use the fan on, key off method, the fan will intermittently come on to try to cool off the engine, it has an ajustable thermostat that will allow the fan to run until it is completly cool.
Anyway, back to what I was saying. The wire that you are trying to hook up is simply a trigger wire. I hooked mine up to the positive wire that turns on the radio. Since the radio needs the key to function, the fan will need the key to function also. The radio has two positive wires, one has constant 12 volts which is required for radio memory and the one that triggers the power to turn on the radio with the key. You can tap into any circuit that utilizes the key to function.
If you want the fan to stay on after the key is off (which doesn't make any sense since the original turns off when the engine is off), hook that wire to the battery positive (+).
Even if you hook it up like I did, you can still cool the engine while the engine is off just leave the key in the "on" position or "acc".

Although most cars with original equipment electric fans allow the fans to keep running after the key is off to further cool down the engine. This may help prevent overheating.

you guys are awesome thanks again

One fan is supposed to be on all the time when the a/c is on. The other fan is temperature-switched.

yeah so, the a/c fan in front of radiator kicks on when a/c goes on but my flex-a-lite puller turns on and off alot. normal?

Sounds normal. However, having two puller fans would be more normal.

hmmm... only 1 fan here.
I have seen the dual kind on some web sites.
Mine is about the same size as my original clutch fan

At least you could get rid of the clutch fan and gain some hp.

yep thx dude

If you hooked it up right, the fan should turn on everytime you turn on the A/C. You are supposed to tap into the wire that goes to the A/C compressor, it triggers a relay that turns on the fan even if it's cold.

fan is installed and cooling nicely! relay works for a/c and temp sensor is working also. thx again!

Nice!!!
