Is the cable of sufficient length to be connected?
I can only compare to my 6 pot but it sounds as if it's the rev counter cable. There's two options, either your rev counter doesn't work or it's been converted to an electronic version

Sorry just 're read the thread I guess that's the far side of where the cable connects. I would find some metal of the right size and fix it in with loctite
