Responding to myself.... this is fun!  Anywho, I tried this PROM out
today, and I'm not sure what the deal is.  I didn't get any DTCs, but it
acted like there was no VSS signal - stalling rolling up to a stoplight
etc.  I didn't get a chance to watch the ALDL data, so nothing
confirmed.

I knew that they changed the pin-in for the VSS in 90 went they went to
the 3.1, but is it possible that, for another chassis, the VSS pin-in is
different, even though its the same engine and ECM?
