Electric Fan Wiring Question

i am using the 3.8L taurus fan which is different from a 3.0 taurus, the 3.0
does not have enough air flow to cool a 302, needless to say if its from a 3.8
then your ok.
first you need the plug connector for the fan itself as you stated, there are 3
wires (ground) (low speed) and (highspeed)
the low speed is by far not enough volume of air and is truly sensless to even wire up, leave it unhooked..
you can get a 20.00-30.00 kit which comes with a relay, temp sensor,wiring,
and instructions at your local speed shop it is very easy to wire up and the
temp sensor is a probe that slides between your cooling fins..

taurus 3.8l highside fan blows over 2000cfm
low side is about half of that

3.0 taurus fan high side about 1600cfm

Did you mount the fan assembly using the strap style mounting brackets?

the taurus fan shroud (GUARD) fits very good to the radiator you wont believe it !
your original fan shroud had/has two bolts on the top, and clips on the bottom to hold it snug.
the elec fan slides down into the clips, and the R.F top bolt hole lines up perfectly to the original..the leftside top needs a hole drilled in the plastic.

one more thing you need to use a shallow head bolt for your w/p pulley
a standard bolt will be to close for comfort, you can get these at a
quality hardware store..(not home depot)
i should be able to get a few pics if you need (weather permitting)

Here are some pictures of the install I did on my car. I countersunk the bolt heads into the WP pulley to give me a little more room. Not quite enough reall for my tastes but it clears. As long as I don't have to change a belt I'll be ok.

I was hoping to use the low speed as the "main" setting and the high for when the A/C is on. I doubt it will work but I'll try. Be sure to get yourself a good high current relay, a 3.99 Autozone special WILL NOT cut it. I paid about 22$ a piece and bought two one for the high speed and one for low. These fans draw a pile of current at spin-up and about 30-40 amps when running, as I recall. So a heavy duty alternator is also inline. If you do all the steps it should work well, if you skimp it will bite you in the arse down the road.

this will help on your installation and part identification problems if any.

I didn't mean to imply that you would cut corners sorry if it sounded that way. Sometime people miss small things and I was hoping to help you avoid that. I followed the setup that was in the previous post's link to a point. But I used the Flex-a-lite #31147 adjustible fan sensor. It is just a temp. controlled switch. I placed this in series with a relay that on is on when the engine is running. When these two switches are both on, it will turn on the "High Current"' Bosch relay to turn on the fan. I don't know what the spec's are on the Jeg electric fan kit are but the inrush current (the current that is first drawn when the fan motor starts to spin) is well over a hundred amps. for a short period of time, and on High the fan pulls a good bit of current. As for the Taurus controls I tried that and followed the wiring back to its source. They all lead into a box that I assume is some sort of solid-state relay. In design it is much like a Dura-spark box with all the "goodies" sealed in an alum. casing with epoxy.

As for t5he alt. I use the HO-7013 from this site. ALT Parts. along with new bearings it was less then 50$ for a 105 Amp alt. that fit with no modifications.

Good luck and give us progress reports!
