i have been having the same trouble. new here trying to find out the same thing.where does the b pin in other models go. my manual says that not all models in that year are missing the b pin. i'm wondering if i could trace that b pin on another model i could tap into mine.

Welcome to AF!

This post is rather old, and I am not sure if the OP ever got it figured out. Your best bet is probably going to be to start your one thread and tell us what is happening. And no, there is going to be no easy way of installing a "b" pin into the ALDL short of getting a complete wiring harness from a car with one.

I bought a scan tool and found that the problems were EGR solenoid, and trans gear selector switch (can't remember the right name.)

Never fixed either, didn't really care enough. Since then, I gave the car to my Father, who sold it to his friend, who will probably blow it up.

Thanks for the follow up! How much was the scanner?

Mine was $600 retail. It's an Actron 9190 complete kit. (I only paid about $300 for it, but that's beside the point.)

You can find much cheaper ones, though. The GP was still OBD-I, it was just a matter of finding a scanner that would actually read from the PCM rather than jumper those two pins. Most of the ones that have an actual readout on them will work, I suppose, as long as it has a connection for the ALDL.
