Looking ECM connection diagram of a cavalie

Good morning to all, the Cavalier workshop manual down and find the connection doiagrams, but they have indicated as rows A, BC and D. while in the ECM connector it is numbered from 1 to 24 (it has two connectors of 24 pins each). I'm not sure which row is which.

Will there be a view of the ECM connector indicating the rows?

Thanks in advance.

Because of the characteristics that this computer presents, I first need to know which model is the cavalier in order to tell you what type of computer it brings if it is from the previous model from 84 to 88 is a type from 89 to 96 is another and from 97 to 2005 it was usually another type the engines are v6 but the last cavalier that came out some bring the 2.2 liter engine and others bring the 2.4 engine that is the same engine of the pontiac Sunfire. The information you need and I can gladly help you thank you very much
