OBD1 scanner port location

I've searched for the OBD1 port location on my 91 Z28 but cannot find it.

Isn't it supposed to be under the dash on the passenger side by the ECU?

Search here doesn't find anything either.

Thanks

Umm, it's underneath on the driver side unless you have an australian car. I believe towards the right of the driver side, right underneath, should be behind a cover if it's still there and the previous owner didn't lose it. Good luck!
