Okay, I tried doing this, running just three wires from ALDL to Diacom
adapter on A B and M. Still didn't work. I guess it must be an issue
with my laptop. 

Anyone that has run Diacom on a 90-91 727 vette please let me know what
brand/model number laptop you used!!! I'm using a Thinkpad 755c. It
works great on my old '85, and has worked on a bunch of '86 vettes with
165's, but doesn't seem to want to work on 88, 89 and 90 vettes.
