I used the the lt1 swap site. Specifically I used the truck 2004 schematic which matches my 2006 harness almost to a T my harness has the blue and green PCM connectors. The rewire had to do with the green connector. Basically I eliminated purple wire coming out of PCM going to gbcm then I took the brown wire coming out of the gbcm and pinned it into c2 connector (green) pin15 where the purple was. I also eliminated the gray wire coming out of the gbcm and put in c2 pin 75 this pretty much eliminated the gbcm. I had to back track what I did it took me a while I hope I explained it right all this info like I said got from lt1swap. Oh yeah the brn ang Gry wires come directly from PCM now.
