Hi Jeff &

I think the idea was to use an OBDII scanner to read the OBDI
system, since OBDII scanners often read OBDI as well. I don't
know this for sure. Under the hood the car is labeled as OBDI
compliant, so likely it's OBDI with an OBDII connector. If this
is the case, your Actron OBDI reader would work on my 94
Bonneville as well. Thank you for your insight.

I have a friend who has an OBDI reader. Maybe all I need is the
adapter cable. I could do without the reader or cable if I only
knew what the OBDII connector wires/pins, correspond to the OBDI
connector, and jump a couple of them for a flashing check engine
light code readout.
