34 pin FDD Connector, maybe?
Looks like it connectsa 5v from the Jamma Pinout (guess it is the bottom side of the pcb?

What wires of the connector would I need to hook up to my cab, based on the solder joints?
I can get better pictures in the morning if need be.

99.9% sure it's the top set, just wanna make sure.

Gonna continue on this thread since this IO gives me nothing but problems lol.
Next up, my NAOMI has a problem with its GPU, (it refuses to boot any games, it's likely a issue with the BGA socket getting damaged during shipping.) Would this affect the IO's ability to output video from the NAOMI? The board works just fine on any old standard VGA monitor, the moment it has to output on my cab I get nothing, the most I got once was a blue line gliding up and down the screen.

You want to ouput 15khz? - Is the jumper on your noami set to 15khz?

Okay, so after some testing, I got it to output blue static, consistently now lol.

Impossible to be sure because unknown Chinese pinout, but you could assume it is like the Capcom pinout and see what happens. Just manually short each wire to ground to test in a game/s IO test screen.
On the Naomi's filterboard, you can find the dipswitch settings in the operator's manual or on the Arcade Otaku wiki.

I figured out which dipswitch, refer to my third post,
my problem now is that now that its toggled to 15khz, it just shows blue lines.

It was hard to parse the specifics because of how the posts were written and ordered.
My best guess at this point is either there's an issue with the filterboard, or else your converter is trying to pass H/V sync when your monitor expects csync (per the JAMMA standard).

My JVS IO has a toggle for the syncs I put it on C, and got the same result
