My '89 560SL has what I assume is the first attempt at an OBD system. Not sure if the correct term is OBD 1 or maybe OBD 0, but it has a nine pin connector under the hood. Where can I buy one or can one be built easily? Also it would be nice to have a listing of what the blink codes each mean.

Thanks.
