that could be anything from 96 and up EX. I can't tell if it's an auto or manual tranny, I know the P2P-A11 is manual, but as far as OBD2a or b, I don't know.. You can look for a production stamp (in blue or black) with a date on the side of the ECU, and some of the ECUs are missing pins on the one plug that isn't used. OBD2a will have a blank 3rd plug, and OBD2b will have a blank 4th plug. This isn't true for all ECUs though, some have all of the plugs with pins.
