Can someone please tell me what I need to do in Editor in order to have an 03' Savana DBC PCM control DBW?? I have an 04' Sierra PCM now. It is the original w/ 6.0 4l80 DBW I am running.. I need to use my Savana 6.0/ 4l80 PCM because I need it to see the 12v A/C request from the 99' Tahoe that the 04' drivetrain lives in.
