Default AC/Heater control unit reassembly help

Hi all, well I successfully tore down my AC/Heater control unit only to find that it's much more different to re-assemble as I did not take pictures as I usually do when doing this sort of job. Does anyone have pictures that can aid me in reassembly? Step by step would be ideal......thanks for tuning in!

Thanks Revi..very helpful as well. I did just a final question on that link regarding how the temp control (on the right side) cable attached to the control pin. I did not see a clevis or anything to keep it from popping off.

Look at the second to last picture in the thread. There is a rectangular slot with a black oxide screw next to the slot. The end of the cable should have a rectangular plastic protrusion that will fit into the slot. The black oxide screw holds the plastic protrusion on the end of the cable in the slot. It is difficult to get the protrusion into the slot given the tight quarters if the console is not removed. The cable may need to be twisted to get the protrusion in the slot. It's difficult to explain but you will figure out.

Oops. Forgot to add that the clip that holds the cable to the pin is also pictured next to the frame in the second to last picture. It just presses on the pin. Not sure if it is really needed but will provide peace of mind.
