If you ever find yourself disassembling a #BambuLab AMS, the first thing you should do is label all the cable plugs sequentially like this - everything in here is black on black on black, several of them are the exact same size, and if someone came along and unplugged all of mine without labeling them first, I'd... briefly consider replacing the whole AMS outright just to avoid dealing with figuring out what plugged into where.
