HVAC Control Module wiring pinout needed

I am looking for a pinout diagram for the two connectors in the HVAC control module. Manual controls, single zone, with heated seat controls. I am trying to interface this module with an aftermarket A/C system for a different vehicle. A full wiring diagram for the HVAC control may be helpful as well. Similar control units were used in the 2007-2009 Silverado's.
