see section 2 , very far bottom left.. C209 bonded to chassis

nostalgia air does not have a code 125,, they do have a code 121 available. code 125 is a make up of code 122 and all of its updates.
to be nice,, i updated post 1 with all this information so the reader has the info on the front end.

this diagram coupled with the code 122 run updates and code 125 updates= a code 125.
there is no known schematic dedicated unto a code 125 stand alone

also i used a three prong to 2 prong adaptor to gain controll over my third prong, thats how i was able to reference ground to a new source.  The third prong adaptor had an eyelet available ,, the kind you utilize the outlet face plate screw to gain the third conductor.
