AN Temp 2 maybe available since your IAT is on Temp 4?  Otherwise AN Volt 3 or 6.

As for the trim pot it will depend a bit on where you are in the world as you dont want shipping to cost more than the part.  If in USA then the avio ones are nice for cost:  https://www.avioraceusa.com/product/miniature-rotary-switch-12-position-finished/.  Knobs are separate: https://www.avioraceusa.com/product/switch-knob-aluminum-red/

Otherwise AEM and Haltech have them, not as pretty.
