It's an american ECU.
Look for a date stamp on the outside of the casing to tell you what year it is.

OR :


Top is OBD2b (left 3 plugs used)
next down is OBD2a
Next down is OBD1
Bottom is OBD0

A designates American in "A01"
Depending on the year of the ecu, the version code "01" will tell you it's first gen and possibly manual tranny (if it's an OBD1 ecu).
