What do you read on the stickers to see what the computer is? I mixed of my computers a 2.3 and a 5.0 also like to know how to read what year it is.

I have the #'s somewhere, but the 5-speed computer should have A_A as the last 3 characters. I think the mid-letter/number can be anything, but as long as it's AA, it's for a stick.

The 5.0 computers should be either A9P or A9L. There are probably a few others out there, but these were the only ones I have ever seen in a 89-93 5.0 with mass air.

Yes, Darin is right too. The upper right corner of the sticker has a code that should tell you what it is too. A9P and A9L work for a stick, and A9M along with some others is for an auto. The code I was talking about is the obnoxiously long one that has dashes in it. There should be something on the end of the code that reads "-A9A" or something similar, as long as it is A_A.
