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!

 

I could be wrong but it seems to me a car that old would have an OBD1 which is the early version. It may be located in the engine compartment fuse box and may involve connecting jumper pins to get the info. This is a wild guess but I have been through it with an older car. Not a Cavilier though.
