I got sent an AC replacement board from Bambu along with a detailed manual how to take out the old board and wire in the new. Unfortunately it is a little bit ambiguous in one specific place.
In step 4 they show a printer which still has a Yellow Ground write:

In a previous step is briefly mentioned that the new revision has removed the Ground Wire:
The new version of the AC board has removed the ground wire, which does not affect the core functionality or performance of the AC board.
And in Step 5 about reconnecting the cable, the printer they use does not have a yellow connector anymore, that would plug into the AC board, the guide fails to mention if the Yellow Wire should be plugged in if you have the connector, or how to otherwise safely tuck it away:

Does anyone here happen to have pictures of their AC board post replacement? I would like to compare the wiring to better understand what to hook up and where.
