05 of 2003 ram 3500 with engine code C, wiring is not the same as a 2003 OR a 2004.. where do I get a schematic?

 

Chilton manual, factory service manual.

 

had the dodge manual for both a 2003 and for a 2004 on my desk, the 2004 sowed no models where a diesel had a j-tech on the passenger firewall. the 2003 did, but the wiring is different.. pulling hairs on this one, has anybody else seen it? I traced the wires from the transmission connector to the j-tech and they are in the wrong places for a 2003... 2 of the wires have already been modified before I ever had the truck in my bay....the bus circuit checked out OK, but the scanner will only connect to the cummins ecm. if I set up the scanner as a 2004 I can see some of the data but not all, the scanner will not show any govoner pressure even when the hydraulic gauge shows 90 pounds, if you wait long enoough it will hit lockup, but never overdrive
