all that matters is PIN 9 at the ALDL connector (bottom left corner). your aldl cable only uses that one pin (and a ground).

ensure it is connected to D30 @ your ECM (blue 30), this is usually a tan wire. trace that tan wire and make sure nothing else is spliced into it.

i usually run a fresh wire for it to ensure data integrity.

disconnect D7 at the ECM (purple wire), it's not needed, but that way you can still use OBD-II diagnostic tools to read codes from your ABS module and whatever else at your ALDL.
