Throw out your test light and gat a data probe as its not just - and + anymore. Signals are sent as ohm values and improper probing can result in catastophic results. We can all thank MB for the R & D on this system. Be very carefull, the ECM worth a few thousand $$$$

I can't remember the exact plug for sure, just follow your instructions.
