Pics of stereo cable in cab need help.

OK, I finally got some pictures. Don't know how much they will help, but here they are. Basically for a long time now I have wanted to get rid of this stereo cable in my cab so I can play all JAMMA boards and have sound. So I need to figure out how to do this. Please remember I am retarded when it comes to electronics. So please explain in small words my puny brain can comprehend.

I am assuming that I simply unhook the stereo cable, and snip the wires so that plastic piece comes off. The one that the stereo cable hooked into. Then hook up the left and right stereo cables into the jamma harness, and hook the ground to any ground on the harness. But here is the small problem. 3 wires are coming from the cabinet, and when you hook up the stereo cable, there are 4 wires coming out. The 3 wires going in are a black and white (both have red stripes), and a solid black. An what comes out of the stereo cable are the 2 wires with red stripes, and 2 solid black wires. So am I going to need one more ground wire so both speakers have one? And exactly how do I fix this so I never need this stereo cable again?

if i understand what you wrote correctly, the single ground wire is probably shared between both speakers already, as both speakers already work. so you will not need another ground.

the best thing you can do is get a 3 position molex that fits what you have to connect the jamma to the existing stereo connector. this way you can go back to stereo if needed and have to butcher up anything.

i see you have a MV1, the wires that go to pin 1 and 4 on the motherboard are your speaker/audio +, with pin 1 being left speaker and 4 right, pins 3 and 4 are ground.

I'd say don't butcher your wiring harness. You seem to have a perfectly good dedicated MVS harness. (Of which I'm a little envious, as I have about 80% of mine, and I don't have the speaker cable.)

First of all, doing anything with that wire won't get you sound. The pin-out on the MVS harness (Specifically 2+ slot boards, as the singles are standard JAMMA) is different.

That said, if you want a way to make your harness fully JAMMA compatible when you use a JAMMA board, what I would do is wire up a little converter board to go between the JAMMA game you want to run, and the MVS harness.

That would restore all the functions such as test and service switches, and be completely reversible.

So, basically, get one of these. (Or something like it) Some wire. And a JAMMA edge connector. Then just wire it up so you plug the MVS harness onto the card edge end, and it gets converted to 100% JAMMA compatible on the edge connector end.

You can find the pin-outs on HardMVS here.

I'm actually going to make one for myself in the next week or so, so I can use an MVS harness with single-slot boards and have everything work correctly. I'll take some pictures.

-Update-
Of course, you could just buy a finished one that will do this, though it'll cost more.

Are you sure this is what I need. this converter says it converts neo geo multislot pinout to be able to use jamma boards? I thought neo geo 1 slot cabinets are wired JAMMA but just have a seperate stereo cable? I want to be able to play jamma boards, and my 2 slot board, and have sound and not destroy my boards. I never want to use my mv1 again. I hate it and it doesnt even play all the mvs games. So what converters should I buy to get them to work? I assume I need 2 seperate converters. Thanks for your help.

You need the opposite MVS>Jamma.

But you need to connect the stereo cable to the harness.

Well, my advice was based on the assumption that it was a multislot NEO-GEO cabinet and board pictured, but in hindsight I think I may be mistaken. Until that's cleared up, I'll just shut my mouth. :P

At any rate, adapting is far preferable to altering, at least in my opinion.

OK, so that will allow me to play my 2 slot board on my cabinet safely. So what do I need to be able to get sound out of JAMMA boards? I don't see a adaptor for that. All I can think of is to buy the other adaptor that lets you play jamma boards on a neo geo mvs multislot wired cabinet. Seems kinda dumb, and unnecessary to have to hook 2 adaptors together. Would that even work? I need a adaptor that will just let me get sound out of a jamma connection that has a seperate stereo cable.

How is your jamma harness wired? Is it already wired for mono? Can you take pics of the jamma harness.

For the adaptor I linked to you can also buy the optional J2 harness which connects to your stereo harness, email them to double check.

I just got home from work and it's late so I can't post pics right now. What exactly do you need to see on the harness? The wires that come out? Or the empty holes in the connector?

I'm obviesly no genius when it comes to this stuff. But I doubt the harness has any sound wires in it. I can't get sound out of any board except my 1 slot, and my Taito F-3 board. And that's only cause they have the connection like the converters in the jammaboards.com pictures. So from what I gather, if I did hook up this converter from the jammaboards website, to play my 2 slot on, I would not get any sound, unless I hooked the stereo cable into the connector on the converter board.

It seems the main reason for buying the converter is to safely convert the sound so I don't destroy the audio amplifer in the 2 slot board. It also sounds like the J2 cable you are referring to is the cable I have pictured in the first post. I believe the converter re-routes standard mono safely, but the J2 cable would allow me to use stereo sound. It also states the J2 cable has quick disconnects that hook directly up to the speakers. This sounds exactly like my stereo cable.

I really think this converter is exactly what I am looking for, but only to play my 2 slot board safely. I just need to find the easiest solution after buying that to get all my JAMMA boards to work with sound. It seems like I would just need some sort of converter likethe ones mentiond, but has JAMMA connections on each side, and the connector for the stereo cable.It would be like a JAMMA to JAMMA converter with a stereo cable connection on it. That way I would get stereo out of any board I played.

THe reason why I said to double check is because your cable is only 3 wires and the J2 is 4 and the pinout for the J2 harness according to the adapter would be different from your cable. It sounds like their J2 connects to the 4 pin header on the adapter and converts to the 3 pin stereo cable for plug and play.
