So i have a 4.0 zj would like to swap in an e-fan. I want it to turn on and off automatically but would like to have an override switch to make and turn it off if water crossing. so what all exactly will i need? like what size realays would a taurus or contour fan work better and how can i wire it to have it turn on and off as i stated above, any help would be greatly appreciated

I would recommend getting some relays from a junkyard (3 or 4 of them) out of a cadillac. That is what I did. They were cheap and they had waterproof housings on them. I don't know what size they were but I have had no problems. The relays were mounted on the firewall (on a little bracket with 3 relays) or the driverside fenderwell. I don't remember. I believe you will need 2 of the relays to set it up the way you want it (the diagram I used was set up for that) and the extras are for spares. Oh, and I think I had to rob a wire off one of the extras to splice into one of the relays I used because one wire wasn't there. You will see what I mean when you get to setting it up.
I will see if I can find the diagram. I think I saw a pic of those relays on here too. Where in SC are you??

These are the relays. Maybe $1 each at the junkyard. Wait until LKQ has one of the 50% off days.. Go get the fan and everything.

I will look and see if I can find the one I used. It is on this forum somewhere. If you look you should be able to find it or one like it. Oh, and I'm not a big electrical person and I was able to do it. The diagram I used had a three way switch and had "auto" (temp switch controlled), "high fan", and "off"(for water crossings.).

Just trying to keep this thread going a little longer .

I was just wondering on a '99 WJ if the factory plug to the eFan would work at all with the Taurus 3.8 fan. (or any other fan for that matter assuming the plug was modified to plug into another fan) Is it's only function to turn on the fan when the A/C is on?

Is the only really good option to get a thermostat relay kit with A/C activation included? Would the A/C activation part of the kit just have to be tied back into the factory fan wiring/plug?

This vehicle is 99% street & highway driven. So I'm only curiously looking into this modification for a little fuel economy benefit. I would like it to work as much as possible like a factory electric fan setup so the fan only kicks on when needed. Especially while driving outside of city streets.

I this the main parts list I'll need basically to do this:
High CFM fan (2000cfm or better?)
Thermostat relay kit

Thanks,
Jeremy

Sounds like you're looking at the same thing as I am, a stock setup but maybe a little fuel economy. The Taurus fan on high is 4500 cfm. There are lots of speed fan controllers out there that hook in to your A/C and are ignition wire triggered. That should take care of you. Also, make sure the fan is from a 3.8l Taurus to get the right fan.

To simplify the installation I was only thinking of wiring it up for one speed. Has the low speed been sufficient enough for everyone using the Taurus 3.8 fan? If it ever became an issue or if I was going to be doing any towing I would then see about adding another relay for the high speed. Is high speed very loud compared to low as the everyday speed setting?

You're talking the difference between hooking up one extra wire or not. What's the issue with that?

Isn't there also a second, larger amp relay needed to run the second speed, plus a switch to toggle between the two?

If you get a controller that is set up to run the, it will have two relays, probably 30A each. When the fan is running and the switch is made to high speed, the fan is already running and doesn't need a big amp draw to bring it up to full speed.

What is this controller you are referring to? I don't recall reading about anyone using one in the previous pages or any other sites regarding this fan conversion. Is this something similar to the Cadillac relays some people are picking from the junk yards?
I'm just trying to keep this as simple and clean as possible. If the low speed is all the engine really needs to keep it cool then the need for high is overkill. Plus that saves any unnecessary draw and wear on the alternator. If the conversion ends up being 6 one way half a dozen the other in regard to wiring for low only or wiring for low with option of high then I'll consider that route too. Let me know what you know about the controller you are talking about and maybe that will help clear things up. I'm not apposed to being safe rather than sorry.

2 speed fan controller

This is the fan controller I'm going to install once we get some decent weather. It has an A/C switch and can actually run two fans, also 2 speed fans. The controller is hooked into a switched ignition wire. The controller runs off the engine temp so it only runs the fan as needed. Straight forward, even comes with fuses and temp probe.
