My 95 (OBD I) has the bungs in it for 4 O2 sensors (OBD II). Don't know why they just didn't skip the EEC-IV and go right to the V with a brand new engine. My 95 Windstar, with the out-dated 3.8L pushrod 6 was OBD-II. So in the same year, Ford took an old engine and gave it a new computer, and a new engine and gave it the old computer. Ford must work with the Governement a lot.... :rolleyes:
