I'm restoring a very, VERY rusted Tekken 5 cabinet. I'm taking the whole thing apart to sand it back to bare metal. In disassembling the guts I came across this cable. It doesnt appear to connect to anything, but it has the same molex connector as found elsewhere in the system. One side is a 9 position, 3x3, the other is a 30 position 2x15. Looking at the owner's manual I dont see it listed, and I dont see where it would even be used. Anyone have an idea?
