The easiest way to get mass air into your truck if you want to keep your E4OD would be to use a 1988 - 1993 mustang A9L or A9P computer. They all had mass air with 19lb injectors and 302 engines, and the A9L is the most sought after computer. But you still need something to control your Electronic E4OD transmission so you need something like the Baumann TCS transmission controller that costs $425.00.(http://www.becontrols.com/pricing.htm)
Some people were able to run the mustang computer in parallel with your stock computer, meaning the mustang computer would run the engine and your stock computer would run the transmission but I have never done this so I couldn't tell ya how to do it. The fact of the matter is this can still be done, it just may cost a little more money to do it. Get yourself a hanes wiring manual for the mustang and wire your harness exactly like the mustang wiring diagram. Hope this helps
