I have a 08 LMM with the option code of NQF I am pretty sure it is a 1626XHD but the schematic provided by ALLDATA for the NQF (or any of the ones listed for my vehicle) is definitely incorrect, for one thing there is clearly a GMLAN connection to the TCCM (twisted pair of tan wires, one with black stripe) and none of the schematics provided by ALLDATA has this.
I really need these schematics
THANKS!!!

Twisted Tan & Tan/Bk sounds like the GMLAN wires

Interesting but not sure that is it, there should be a wakeup lead and I do not see the front differential control leads
EDIT, is the HSLAN the same as the GMLAN? I would assume the HS stands for high speed, but none of the pin numbers are the same on the schematic as the PDF

Sorry was looking at the wrong module, dang it! I assume the front differential servo is on another print, this helps THANKS!!
