This is the module located by your battery in the engine bay.  It controls your injectors, your spark, and your alternator voltage.    This one is used, tested good.   
 
What does this fit?
Pretty much any/all 2.2 Turbo I or Turbo II cars built from 1985-1987.     This will ONLY work on turbo cars.  
 
Note:  No core required.
