That OBD-II EEC-V on your 95 Windstar probably cost a small fortune to make at the time (relatively speaking), since at the time Ford was making gobs of OBD-I EEC-IV and ramping up production of OBD-II models on a new production line. Capacity was very low at first on the new OBD-II model as they were trying to get the process right, explaining the small number of vehicle lines using it in 95. There are quite a few differences in the manufacture of the EEC-V compared to the EEC-IV (double sided reflow, new thermally conductive adhesive, spray coating instead of dip coating, new ring casting/heatsink and connectors). Of course, they all had to use it in 96 so the line had to be "proved out" before being completely dependant on the new process for all vehicle lines. There's more to launching a new product than flipping the switch on the new line and walking away.
