Help with Sega Ver. 2 I/O Jamma Converter

[8bitforlife]

Going to have JNX make me an adapter for Sega Ver. 2 I/O Jamma Converter to cps2 so i dont have to unplug everytime i switch games.

But I'm having trouble finding out pinout.
Sega Ver. 2 I/O Jamma Converter is going in a sega blast city. I gave up trying to find a 2nd capcom io at a decent price.

Any help would be appreciated.

Are you talking about the Sega I/O BD JVS to Jamma (838-13683)?
If so here is the manual for it.

But reading online it appears that the pin out may not work as described.

no it's the rectangular black box one not just a bare board

Ahh, okay.
I could only find one picture online that showed the Ext I/O (Kick Harness) it looks like the same JST NH 14 pin connector as the (838-13683) Rev B. If that assumption is correct, I would think that Sega would have maintained the same pinout.
I would try jumping the pins with some wire and confirm the pinout that way.
