All 4 of the NNC's that I got my hands on (2 for me, 2 for my buddy), all had that same rat's nest. It took me 20 minutes to unravel the first rats next because I didn't want to pull something out I shouldn't have. But in the end, it was just stuffed in there. Not even going to bother trying to hook up whatever that is. Making my own JAMMA loom. As for what an NNC is supposed to actually look like, I don't know. But what you have after pulling that out is exactly what I have, deadly imported Chinese mold and all.
Can you (or anyone else that picked up an NNC in this group buy) remove the front panel. There is another AC switch there. Can you see if the frame is cut haphazardly around the AC switch?
