I have an 84 S-10, iron duke and TBI that I drive every day-but I don't know if it's an 8062 or a 7165. With the dash in the shape it's in, I'd just have to try connecting with each set of files and see what came up. Too much risk in the whole dash just collapsing if I were to start pulling it apart to get at the ECM.
I do have the 8062 and leftover harness bits from the truck, too. I can't really twiddle inputs too much with it, so I can't simulate a running engine. However, I could probably connect to it.
