My code reader would connect to the bad pcm....and like zeejay said, the 97 needs no additional programming prior to installation....not even mileage nor VIN.
When the downstream o2 sensor wires short, ( a common issue) they will most likely blow a 15 amp fuse in the PDC. Dont know what happens if the sensor develops a high resistance internal short.
