wiring vs operating system

[780ripper]

hi guys,

i have 2 pcm's for my truck, each was professionally tuned by a different person, both pcm's are red/blue, one is a 2001 os 12208322 and the second is a 2002 os 12216125, but only the 2001 pcm works in my truck, its dbw. are there different wiring diagrams available for either one of these pcm's? i am trying to figure out if either can be converted to dbc?

Maybe the schematics at this website will help:
