1995 E420 CEL, How do I check?

The dealership told me it's OBD2, even though it's a '95. So I'm looking for the OBD2 port for the scanner and I can't find it under the dash. All I CAN find is 2 diagnostic ports under the passenger side hood near the firewall.

One port has an 8 hole pin out with a small button and a light. The 8 holes do not fit the actron obd2 scanner, the are aligned in a straight line.

The other looks like a Formula wire harness connector, it's circular not 8 pronged like the normal OBD2 connectors I've seen. However, this one is located near the ECU (which in located in this battery looking thing under the hood).

Anyhow, my question is where is my OBD2 port so I can plug the scanner in? I'd like to check my code for free instead of paying a stealership.

E 320
My 1995 E-320 is NOT OBD2 I don't know when we switched over. I also owned a 1995 740IL and it was not OBD 2.

If it's not OBD2, then I guess the only option is the dealership or something with a diagnostic tool specific for Mercedes?
