Reading check engine codes, 94 cutlass

Does anyone recognize the connector below thats in a 1994 Olds cutlass supreme. In the article below it tells how to jump terminals A and B to get the codes but the location of my terminals inside it are in different locations and I don't know what terminals would be A and B. Our local auto zones only check 1996 and up.

This is the article

and this is a jack from a Internet picture (not mine) but I have marked where my terminals are.

I found the answer in a Haynes repair manual.

NOTE: It should be noted, however that some models with a 12 pin diagnostic connector do not have a terminal B present in the connector. On these models a scan tool is required to access these trouble codes.

Thank you to discnik for replying but it looks like I need a scan tool. I have PM you.
