EEC-V cougar to EEC-IV 5.0 HO, can it be done?

The diagram posted earlier sure looks like it has 60 pins.
Also, explorers and mountaineers do have the EEC under hood like shame mentioned.
That is a good point, I forgot about the smog puppiess. I live in NJ where that would also be a problem (reverting to an older system). In Texas though, that might not be a problem as some states (especially in the south) do not have emissions. If that's the case, then you could still swap in a 5.0L from a explorer/ mountaineer from 1998 and newer, or you could switch to a 4.6L. Obviously in those cars (MN-12's) working on any type of V8 is a difficult task because it was never meant for a V8. The 5.0L was shoehorned in there, and the 4.6 was that times 5, plus it's more difficult to work around due to the width (exhaust manifolds and headers require K-member removal, intakes require hood fabrication), and of course, mods are expensive. Want to put headers on your mustang cobra (or any fox for that matter witht the 4.6)? No problem, FMS and BBK offers bolt on sets, shorty or full length. Want them for an MN-12? You can only get them from Kooks in Long Island (through SCCoA) or from ART. They cost roughly twice as much as the mustang counterparts, and require the aforementioned headache to install (unless you put them on the motor before it goes into the car, but God help you if those bolts come loose). Want to use the tumble port heads? Not a problem with the fox because there's plenty of hood clearance. In an MN-12 you need a custom hood setup to fit the tumble port head intake. Want to hook up a 5 speed? With a 5.0L you can just get the 3.8L SC car's tranny and parts and hook it right up. With a 4.6, you need a custom lengthened tailhousing and slave cylinder (since the T-45 and T-56 isn't long enough to fit an MN-12).
