Pretty sure my ecm went out. The number on mine says: F0SF-12A650-L2B. Which is the right one? I see there is an LB, but not an L2B. http://www.rockauto.com/en/catalog/ford,1990,thunderbird,3.8l+232cid+v6+supercharged, 1140387,electrical,engine+control+module+(ecm+comp uter),2896

the part number is useless, the hardware code and the catch code are the import numbers to go by
