I'm Awesome
I wasn't sure if it was some sort of oddball issue with my truck, but I found a few more people with the same problem so I'm ruling that out and figured I'd start a thread in case someone else has this issue.
After I 0411 swapped my 2000 K2500 I had no activity on my o2 sensors. Turns out they needed a ground reference from the computer since they were not case ground sensors (case ground use the flat plug I believe, mine are triangular).
To fix this, you need to tie the low reference wires (C1 26 & 29) to C1 63, which is a ground reference.
