So did trying to ID it as a 1998 Maxima work?
Some earlier years of OBD2 cars didn't have all it's systems accessed by the under dash 16 pin connector yet, and still were using some proprietary OBD 1style connectors for certain systems.
Here in the mid west , most old Maximas are long gone, or have lost a lot of weight due to rust rot and now could be considered Minimas,lol
