OBDII or Not

What is your question?

As I last stated in my original post about this new rig to me I cleared codes and have not come back. What is confusing is that has OBDII connector under dash and also has diag link box for TE1 and E1 ability for code retrieval. Was manufactured in 09/94. Why does it have the OBDII connector under the dash? I did attach my scanner and was able to retrieve codes and clear. Thanks for any info.
