Yes, Chris sold his car...
Thanks for all your replies guys! I have since had my old chip sent to me with a new program, and today we will go for a third shot. Also poured in some of that "Guaranteed to Pass" junk in the gas tank. Wish me luck!
I do in fact have a cat in its original location (where the stock one would be). I seem to have got the visual part squared away, and a fake CARB E0#. What I am failing is the sniffer itself. So this time, if it fails, I will take whichever reasonable "hookups" you guys have!

PM me your #s, just in case, PLEASE!!! This has been a nasty nightmare...
