never intended to become an obd1 expert from the owners manuel ........ just need to know where to plug the scanner into.......since i was just made aware that you can even scan a 90 suburban......just incase the kid at autozone has no clue

most stores only do obd2.... obd1 is too complicated for parts counter boys .... on your vehicle though the owners manual should have a way to check trouble codes with no plugin what so ever, you just do what it says and it will blink the check engine light to give you the code
