I have a Sega Naomi Universal cab with no game.
I put a PC in it for emulation and got a JVS-PAC2 to connect everything.
However it says it can't find a jvs board. After some research, this is because I don't have the IO board powered correctly. I know where the 5v in and 12v in are located on the board and my harness plugs into them but I'm not sure where to plug the other end into.
Can someone send me a photo of a correctly wired power harness on the Naomi universal?
Thanks

You just need CN7 (+5V) plugged in for the IO to work. The wiring harness runs down the left leg to the PSU.

OK thanks. That gave me the hint I needed. This cab had some custom work done to the wiring. But I found it after some searching.

Btw, what is the 2 pin connector for? I presume its not needed?

Coin mech or coin counter possibly?

Maybe. The coin mech seems to have a ribbon cable. I've no idea where that plugs into. Maybe I'm missing a board.

But it doesn't matter I suppose. I have my controls working.
Thanks.

Correct. The ribbon cable would attach to a credit board.
