Yep, that's what I have heard also.
The 94/95's are not a fully compliant version of OBD-II. But they are pretty close. I don't know what the differences are, but I think 96+ are fully compliant. It may have something to do with the ignition being external vs. internal on the new models. Just a guess.
Hope that helps.
