OBD-1 Connector

[PAULSPEED]

Trying to help a friend with his 1988 911 Carrera.

Could not locate the OBD connector.  Any help?

This could be a european car.  The Vin number on the door was scratched off and there is no vin number on the top of the dash.

His DMV vin number is WPOEB0917JS161141.

Car has not run in about 6 years.

I would be VERY suspect of any vehicle with VIN numbers defaced or totally missing.

 

1988 Porsche Carrera obd port location

Your 1988 Porsche Carrera, being an older model, won't have the standard OBD-II port that is found in vehicles from 1996 onwards. Instead, it will have a pre-OBD diagnostic connector. 

 

1988 Porsche Carrera Diagnostic Connector Location:

12-pin rectangular diagnostic connector: The 1987 and 1988 models utilize a rectangular 12-pin diagnostic connector.

Location: This connector is located on the ECU mounting panel. It was intended to be used with the Porsche/Bosch 9268 interface, also utilized on 944 models of that era. 

Important Notes:

ECU Location: The DME (Digital Motor Electronics) control unit (ECU) in a 1988 Carrera is generally located under the driver's seat.

1989 models and later: Porsche began using a round 19-pin connector in the 1989 models, which is located under a cover at the passenger seat.

Adapter Needed: To use modern diagnostic tools, you will likely need an adapter cable that connects the 12-pin diagnostic connector to a standard OBD-II port.

Thank you for your response.  There is a box under the drivers seat.

All connections were connected and there was no blank connector.

I did not look under the passenger seat.

Try looking along the lefthand kick panel/carpet, you may need to remove it to see it.
