EFI cars have a full EEC II unit, 85's have one that runs the EVAP system as I recall. It was also supposed to run the "TSAD" (Two Speed Accessory Drive) a "underdrive" pulley system that Ford anounced, but never produced.

Gregg,
   There is no OBD on your car, that came some years later. You can do a scan for basic codes with a simple meter.
