That is what I thought, Just wanted ot make sure.






I'm lost. The old body style (OBS 96-00) has a PCM, so I don't get it.

So what cable are you using ?


Do you have a serial cable 9-pin -to- OBDII connector?


What software are you using?


What year vehicle the 2004 with the class 2 communication or the new GM VLan?


Just curious as I'd like to do this myself...might consider the autotap but wondering how you plan on doing it...
