Would using a different relay work?
UDPs and E-fans

Yea, you'd need one of those heavy duty relays. Something that could handle the amount of start up amps. Some of the Mark VIII sellers on ebay sell them.

How many amps?
This might help?

I got the fan today, it was from a 1995 and over 100,000 miles, is it still ok to use?
Guess it should be. They are OEM fans that are meant to last for a while.

Thanks, I will be doing this along with the UDPs ASAP. Anyone else have other input on this, any help would be greatly appreciated.

I got a couple questions about the controller and the fan.
1. Where would be a good place to connect the ignition switched wire?
2. Do I just "cut" the A/C switch wire with the + wire on the wires to the A/C clutch?
3. What do I do with the second fan lead, do I also connect it to the fan?
4. If needed, could I just replace the relay and fuse for ones with higher amp ratings?
5. Why does the fan have 3 wires comming from it?
6. What would be a good temp to set the fan turn on?
7. What are the "zip-tie" thingies called
I know i am asking alot of questions, but I just want to do the job right the first time.

Hmm, sorry I can only answer a couple of your questions.
5. One is ground, the other two are low and high speed. On mine, I think the blue wire was the high speed. Just hook the wires up to a battery, and you'll see which is ground, and the different speeds.
6. On F150online, I've heard that our engines like being around 202F. You could get an infrared thermometer, and point it at the radiator, and set the controller until the radiator is around that temp. Then again, you said you had a lower temp thermostat, so I don't know exactly what that would do.
7. I've always just called them zip-ties. If you call your local Autozone, and tell them you're looking for zip-ties that fasten e-fans to radiators, they should know what you are talking about.
As for the other questions, I honestly wouldn't know how to answer them. Why don't you go on over to F150online.com. There's a couple people there who have used relays and what not to set up their fan(s) and would know how to answer your questions. I used a DC fan controller, so that made installation much easier.
