A number of us have the wiring diagrams. I have them in a hard copy Service Manual and in the GM Service Software that I bought. The problem is there is no one schematic for what you are looking for. The shematic is broken up into pieces across different types of functions so somebody has to go through the complete manual copying each applicable schematic.
The 7.0 Litre Engine Control Schematics are broken down into 12 different figures. One figure just covers power and ground for the engine controls, another just covers 5V reference circuits, etc. Engine electrical is covered in an entirely different section.
Your best bet would be to find the thread on the C6 parts forum that is selling the DVD manual. That way you can go through each function and make sure you have what you want. I bought my DVD for $50 a couple of months ago.
