Hi,
If you are looking for the data link connector (DLC), it is in the vehicle under the dash on the driver's side of the vehicle. It should be visible.
I attached a pic below showing the location. See if you are able to find it. If you can't let me know. Also, here is a link that explains how to retrieve codes from the OBD1 system for a GM vehicle.

Let me know if this helps or if you have other questions.
Take care,
Joe
