I have a couple jamma harnesses from TQ or some place like that and I noticed pins 27/e are not wired. These are normally "ground" according to the Jamma standard but the way it is wired from the factory has nothing on 27. I think things like Pandora's etc use 27/e for something but I am hooking these up to MK 1-4 and SF2CE series games (hyper fighting, redwave etc).
My question is: Is 27/e needed for anything for the games I'm planning on playing or should I just leave it un-wired? I could run it out of the harness and ground it back at the power supply if I need to I suppose.
Other ones that aren't wired are the Key Slot (Don't care), Coin Counter (Don't care) Lock-out coil (don't care) Tilt (Don't care) and oddly enough Video ground at 14.
The video harness with the plug however does have a ground it just takes it from 2/B. I can plug it right in I believe.
I am not sure if there are any mods I need to do to the harness or not at this point honestly.
Any help would be appreciated.
