That link shows you what you need, but if you follow it, you get to the part with the 15pin connector that "stays with the pcb" which you never get with the pcb. On my original harness, it is so wrapped and zipped tied together, it is easy to mistake as hard wired to the harness with the other players wires.
So, you look up Bob Robert's connectors and they are all .100" instead of .098" which over 15 pins will no longer fit. Over 4 pins, the difference doesn't matter. It adds up around pins 13 and out. 13, 14 and 15 for sure needed a bit of bending to be even close, so I never was able to fully fit the connector. I wasn't going to bend pins on my boards.
Bob Roberts does sell one listed for konami, but since none of his parts are .098" I don't know if it will work or not. Mine from jamma boards was listed as/for konami specifically and didn't work. (They let me return it, which was nice of them.) I was told the olders boards needed the .098" and no real indication of when a change happened.
