Default Is there an actual obd connector on '91 D21?

I know about the codes on the computer under the seat.
A friend has the same year truck and his county is trying to say he's supposed to have said connector (state licensed inspector aka "The State").
So, does it? Where?
Thanks
W.

No such beast on a 1991. They didn't have OBDII connectors till late 1995.

OBD I codes and instructions for reading said codes...

Nissan OBD I codes and retrieval instructions.

I don't know if this is common knowledge around here or not but hey, let's put it out there anyway for those who don't know.
