Good day, dear partisipants of this forum.

I really need help to understand where the port/plug for electornic diagnostic in Chevrolet Cavalier RS 1993 is located.
Unfortunately, I have limited info avout this truck in my country. Finally, the service station where the equiment with such type of port/plug is available was found. But currently anyone has no clue where to find the plug to proceed with further diagnostics of sensors.

I will highly appriciate any reccommendation or your experience with such problem.

Thank you!
