379 wiring schematic

[Luckyjayb]

Looking to try and find the schematic on a 379 2008-2010 model years. It’s a buddy of mine’s truck and the previous owner butchered the wiring behind the dash. Something is wired wrong on the j1939 connector because it will not communicate that way and the only way to connect to the engine is directly via weatherpack connector on the cm 871.
Thanks in advance
