it seems straightfoward. I'm close to pulling the trigger on a DBC harness and just saying I'll figure out the rest when I get to it, or give in and convert to DBC. for my build, the DBW pedal would make life easier than the cable setup and I already have the TAC and harness

I don't have a complete answer for you, but in a few minutes of research, I found this:
The '97-05 Corvette has Red and Blue connectors pinned very similar to a 2002 Camaro. Differences are:
Corvette DBW has:
Blue - Pin 13 - Requested Torque Signal (Orange/Black)
Blue - Pin 14 - Throttle Actuator Control Serial Data (Tan)
Blue - Pin 15 - Throttle Actuator Control Serial Data (Orange/Black)
Red - Pin 5 - Delivered Torque Signal (Tan/Black)
The 2002 Camaro DBC has:
TP Sensor Signal - Red 24
TP Sensor 5V - Blue 8
TP Sensor Ground - Blue 60
The Corvette does not use those lines, but does list Blue 60 as a Low Reference; not sure what for.
I don't know if that helps you any, but those are the main differences between the DBW Corvette and DBC Camaro from those years.
Looking at a TB pinout, they use different pin names like TAC Motor Control 1 and 2, but I don't see them listed in my diagrams. You might have to compare the complete electrical diagrams of those cars.

I'm also trying to dig up the Silverado vs Escalade wiring diagrams for 2002 to cross reference the DBC and DBW engine harness and pinouts. I'm 90% committed to converting a early DBC ebay harness to early DBW setup, if I succeed I'll start a new thread with clear details for future newbies like me

By "few minutes research" I mean looking it up in the printed copy of a document I bought years ago titled "Custom Stand Alone Wiring Harness Guide for the GM Generation III" Copyright F-Bodies Inc 2007. I bought, downloaded and printed a later one titled "Custom Stand Alone Wiring Harness Guide for General Motors Gen III and IV Engines" Copyright F-Bodies Inc 2007. I can no longer find them with Google. The info I gave you was in the first edition; while the second edition was much bigger, it dropped the 1997-2005 Corvette info.
Let us know if you can find a source to buy them. Since they list a Copyright, I can't just scan and post it here.
