Efans from 2010 on 04-08 5.4?
Just go to any Ford dealer and order an elect. fan Assy for a 2010 F-150, with just a very few small alterations they will fit the 04-08 Rads. A DC Controller FK50P is what you want to control them with. The Fans and shroud are about $200. The controller is about $150, I for one would not trust any other controller with these fans. Only fabs that I am aware of are only a couple of L shaped 'hooks' to secure the shroud to the bottom of the Rad. Bear in mind, I haven't done this yet, I expect the fans to arrive by the end of the week, I already have the controller, so, bottom line, I'm only going on other posts I have been reading. Part# for the fans is 8C607 (RF-252). I know...weird #, but that is what Fords computer shows for it. Best info I have for now !

Also, if anyone can figure out either the part number for the factory harness that runs from the fan motors up to the fuse box that would be a huge help as there is a large gauge, two connector plug that plugs in at each fan motor. The local parts counter told me there were a bunch of different part numbers and they wanted to see the part so they could compare them. I tried telling them to just go pop the hood on a new one in the lot but don't think they appreciated my suggestion.
Are you sure the FK50P is going to be big enough? In the 2010 F150 there are 2 40 amp fuses (I am guessing one per fan) and 1 25 amp fuse (possibly for the factory controller?). I would think that the FK85P would probably be a safer bet for these in case they do draw more than 25amps each, in which case you will be overloading the FK50P controller. I think I may go ahead and order an FK85P now and order the fans once I get the controller. Please do post up pics and details as you go about installing your setup.

Save your $$ The 50P is big enough for these. Also forget about a harness for this setup, just fab a harness and parallel the two fans into the controller as you would any double fan setup. AFAIK there is no way to electrically integrate these into the 04-08 PCM.
The factory harness that I am trying to find is a simple plug on one end, guessing about 10 gauge wire for about 10-12 inches then terminates in the fuse box under the hood. I don't care what kind of connection is on the fuse box end as that will be cut off to connect up to the FK85 (still not quite comfortable running two fans that the factory fused at 40amps each on a single controller rated for 50amps, especially for a $25 difference).
I didn't look real close at the motors, but if the casing came apart, there may be away to splice the wires and bypass having to have the harness, but you would have to wire it right or they would run backwards. I think once we figure out the mounting part of the fans, we can work out the electrical. To me it almost looks like it almost a drop in as far as the shrouds go.
Poonjahb is right about the harness, you would have to splice on to the end anyways, as the wires wouldn't reach the power box, the 2010's are mounted right on top of the radiator. But the harness would make the plug in a breeze as the fan end goes.

If I can get my buddy to let me play with his a little bit I will try to figure out the connections on the fan so we know which is power and which is ground. Hopefully there might be a part number on that power harness too. I'll see what I can find this weekend.
They don't - but they do offer an 85 AMP version

Don't rule out the Spal PWM-V3 contoller. It has soft-start on the primary fan as well (eliminating the inrush current concern) with a 30-amp max continous capability on the speed-controlled channel (with an unlimited current capability - determined only by the external relay, wiring and fusing) on the secondary fixed-speed channel.
Readily & quickly available and great build quality. Great programmability, indicators and support.
FYI Sam - you should be giving props to Digital Market, because that is where most of yer info came from ... but I do applaud you for giving this a shot
MGD
Well, whoever is the first to do this (Sam, I'm looking at you) please take plenty of pics and post them during the install so that the other hundred people that want to do this have something to work off of. I've got to go pick my truck up from getting the AC fixed, so I may stop by the parts counter again while I'm there to see if I can get any more info out of them on the harness and anything else we may need/want to do this mod.
And to answer an earlier question above...a FK50P will run both fans, I stumbled across a post where they were doing it without any problems. So we (I) wait.
