I have a 2003 Sea Breeze also and the post about the OBD II being on the right side is correct and it is hard to find. Mine actually had a cover over it plus wrapped in tape partially so real hard to see up there. Take a flashlight and the small panel below the steering column off that is attached to the bottom of dash with 4 screws. That will make it a little easier. Also the black between the body and hinge might be caulking or a rubber gasket, either one should be replaceable.
