I'm not familiar with vans, but on trucks, you just pull the connector (10mm bolt in center) and the 2 nuts, and then slide it into the engine compartment & out.

What's the difference? Electronic Control Unit (ECU) = Engine Electronic Control (EEC) = Powertrain Control Module (PCM) = Motronic Control Unit (MCU) = "the computer", right? 
Ford has used all those names for basically the same part. I guess you could call it the Engine Control Computer (ECC) if you want...

Hey Steve83, would it be better to use a later model truck ECU or the older Mustang computer for converting to Mass Air? Don't know when Ford went to OBDII or if they connect to older connection blocks. Haynes manual doesn't show it. Any ideas? Thanks in advance!

I always use the EEC that goes with the engine I'm using. The easiest MAF conversion IMO (and certainly the easiest to maintain & repair) is putting an OE MAF engine COMPLETE into your vehicle. That way, you can look in the same manual everyone else uses to work on it, and you can even find how to install it. 
That's what I did to my truck and a friend's '75 Bronco, both of which you can see in my signature link.

That's a good idea. Cooked the engine in my van last month. Mechanic said previous owner /carlot had wired oil pressure gauge to read high when really not much there. Found a 2000 Exploder 5.0 w/28k miles then orderred a conversion kit but it went on back order again. Thought about using the Xpl ecu cause I have the complete harness but can't find a Helms manual yet. Already have info on the Mustang. What do you think?
