Identifying this EEC

[hotrodt]

How do I identify what car this computer came out of ? It's got a $#@%load of numbers and letters on it. Supposed to be out of an '89 gt auto

 

[hotrodt]

numbers are EEC-IV SFI-MA12A01J25
F3ZF-12A650-DB
61SM12AF14-AC 96017-12
AND THEN IN VERY LARGE NUMBERS IT SAYS A3M1

 

[Blown83GT]

A3M1 5.0 89-93 Mustang MAF / Manual (see note 1)
