2001 8.1L (L18) PCM Pinouts

Of course Gm Upfitters does not have the 01 and 02 manuals anymore and in 03 and up they were different harnesses. Ive tried Prodemand and MotoLogics for pinouts and they are different in areas on the C1 and C2. Id like to see AllData as Ive heard they are the best at labeling as well.

I need the C1 and C2 PCM pinouts. Does anywhere have these? Im not buying a harness. Im making this one stand alone. And of course you cant find nothing about these engines anywhere. Ive owned one since 2004 and love it so I know how hard it is. The struggle is real. Ideas?
