My '88 560SL has a nine pin diagnostic port under the hood. I seem to recall reading on one of these forums that you could build your own to read the light pulses to determine problems. My particular concern right now is with the SRS light being on all the time. Can anyone provide me with information on how to build a reader or where to buy one?

Thanks.
