Building a 4900 Tri drive truck having wiring problems

Had a serious wreck with a 2007 4900 Tri drive log truck with cat NXS motor three years ago.
I bought a 2010 4900SA Tri drive complete frame, Bought a nice 2009 4900 SA cab and I am in the
Process of putting all these parts together. The motor and transmission checked out ok.
When I started hooking up the 2007 truck and engine electrical harness to the 2009 cab the ECM fuse from in the battery box blew. Disconnected all the electrical and isolated it to a 40 pin harness plug into the fire wall. After looking closely at the plug some of the pin and wire numbers don't match. Can someone tell me the function of this connector. I cannot find a schematic or any info anywhere.

 

Went to Edmonton Western Star and shop Superintendent
Gregg helped me out. He supplied me with print and went over all the wires with me and we figured out the wiring changes to connect the 2007 harness to the 2010 cab. Thanks for his help.
