This is a 20-pin replacement ribbon cable for the Sound board to work correctly with the Mortal Kombat II PCB. This is exactly what you need if you have lost the original power cable or bought the board separately and it didn't come with any wiring. Don't forget the
power cable! The other cable required for the DCS Sound Board to work is the (hard-to-find) 9-pin
power cable for the sound data between boards. I provide that separatly since often you need one or the other.
