The plugs all changed as well as the fuse box location in 04.The motor swap would almost be easier than the dash and frame harness swap. The you will also need the keys from the pcm donor truck or you won't even be able to get it to crank or run because of the pats system.
I see what you're saying ... I'll go ahead and put the 2001 4.0L in my 2004 Ranger. If I get a 2004 PCM and the wiring harness that it was matched with from the factory then I don't see why it wouldn't work. And as far as the PATS go, I already plan on swapping out the ignitions.
After I do the conversion, the 2001 Edge will have a primo 2004 3.0L with a little over 63K miles and I'll give you first dibs on it if you're interested.
btw ... my 2004 auto trans is in mint condition too.
