15 to #9 on obd plug- 59 to #2 obd plug-blue #20 to#16 bod plug-#4&5 from the obd plug to ground. mine is out of a 97 Riviera, so I'm thinking they must be the same. This is wired for a '98 computer. Phonedawgs can help you better.

To scan the PCM of your 97 3800 you only need data on pin 2, grounds on pins 4, and 5, and unswitched power on pin 16.

The tan wire is not needed.

For the data wire the standard seems to be Purple and runs to pin 59 Blue.

I can confirm that I can connect to and scan my 97 PCM with only these wires connected.
