The info, including diagrams, pinouts, and specs, is very well
documented in the Mitchell manuals, available, (here anyway), for free
at any public library.

All-Data has an on-line service, but lacks detail and reliabilty, as
they tend to generalize. ie. I had an '95 GMC JIMMY SLT, that was spec'd
with the PCM in the right place. Unfortunately, it wasn't a PCM, but a
VCM-A, which integates the ABS into the VCM. Mitchell had it right,
All-Data had it wrong, and deliberately restricts the modem to about
2400 to run up the connect charges.
