That's an OBD2 STYLE port.

If that's from your 96 it's an OBD2 car and port.

Thanks. My Jet DST wouldn't read the pcm until I rebooted the laptop with the usb keyspan plugged in. I thought the previous owner might have swapped out or modified the port since this car had an obd1 pcm in it when i bought it. Thanks for the verification!
