A few people have been a little hesitant on getting an efan because of the wiring. Hopefully this will help make it a little easier. I have the flexalite 180 fan with a spal v-3 controller. Some controllers are going to be different but this should help regardless.

Here is my controller

Here is my fan

These are the power and ground wires going to the fan...my fan had a female connector on it and i just cut it off.

Here is the power connection for my controller

Here is the fuse going to the power connection(mine is a 30A)

Here is the ground for the controller hooked to the right of the battery

Here is the ignition source wire and the a/c clutch wire. Ignition is the orange one and the a/c clutch is blue.
For the ignition, find a fuse that only has power when the truck ignition is on.
For the a/c, you can directly splice into the a/c clutch power or just get a fuse tie in and tap into the a/c clutch relay. I don't know if the a/c relay differs from year to year, but when you pull the relay out, tap into the last one on the row with three male connectors. It will make sense when you pull the relay out.

Here is half of the engine bay...directly above the power steering cap is my temperature sensor for my controller. (It is the gold piece with two wires coming out the top.)

I hope this helps.

 

what shroud did you use?

 

the flexalite fan and the shroud come as one single piece

 

Thanks lmrjason! This will help a great deal, and I actually understand how I have to wire it now!

 

I'm still confused. Probably because I have a different controller, I'm just confused as to how to wire the controller to the A/C.

 

I just shoved the end of the wire in the hole a forced the relay back in and that actually seems to work best for me.

 

Now a little off topic, but Im confused about how the cooling fan works. Is the fan working to cool the coolant running through the radiator, or the engine itself.

I may be over thinking it, but whats the whole point of the thermostat/controller. Why not just run the fan when ever the ignition is hot?
