    Corvettes are all DBW ... some trucks are DBC.

    Are you certain that you have the skill sets to undertake this project ? Despite your claims in post #4, you don't seem overly familiar with these systems. It may be a better course of action to either leave the car as is, or to retain the services of a reputable professional.

    To answer your most recent question ... some of the 2004 full size vans were DBC.

    That's what i have found too, yes i have the technical skills to do it, its just as you said, i am not overly familiar with the systems. I don't know everything about every PCM and OS made as you seem to. Though I am learning quickly.
    I understand that my questions make it seem that i am confused with how the system works, I am not. I am sure that you didn't know everything when you started, this information doesnt seem to be openly published and available.
    If i had some nice factory service manuals for everything im sure this process would be much easier. But, alas i must learn the hard way. I am not some hack who is going to use butt connectors to hack together a system.

    I appreciate your concern, but i assure you, i am more than capable. I am a mechanical engineer with somewhat extensive electronics and programming skill, i just don't have the time to mess around with it and learn from my mistakes.
    I need to know it will work the first time i do it. I am home maybe 2 weekends a month, the rest of the time i travel.

    GM factory service manuals ...

    www.helminc.com

    The DVD format is not currently available (some say it will never be available again) ... GM hasn't released a DVD since 2011 ... it was the best bang for your buck at around $400 (covered a decade of most models).
