Default 2011 1500 4l60 tcm pin diagram

Does anyone have a diagram they can share with the TCM pin setup?

I have a 2011 1500 w/t with the 4.3 automatic. I just got the U0101 TCM communication lost error along with stabilitrak, traction control warnings and loss of gear selector indicator. I swapped out the TCM and have the same problem which leads me to believe I have a wiring issue. But I don't have a diagram to tell me which pins can get me voltage or ground that will help me see what wires might be broken. Any help would be appreciated. Thanks

It would be great if the diagram had expected readings for the various pins. I have checked voltages with the truck "on" but not running. I have readings at most of the pins but have 8 pins with no readings at all, either voltages or resistance.
