Yes.
Bob Roberts sells all kind of connectors. You can buy them from Happs. There are wiring connectors all over the net for arcades. I don't think there is any store you can just walk into and buy them, you have to do mail or internet order for them.
If it's the edge connector, I suggest that you buy or make the tool to remove the clip out of the harness. That way you can make a new one and just run the wires where you need them. Bob also sells those tools for removing molex pins, etc. They come in real handy with repairs like that.
