IDC Connectors 0.156" Pitch, for 22 gauge wire
Replace those burnt out connectors to give you a perfect contact once again.
Used in many makes of pinball machines including Williams, Bally, Stern, Data East, Sega, and more.
Williams/Bally reference #5792-10817-xx
These are easyish to cut with a stanley knife so if you want a 2 - 6 connector I would suggest buying an 11 / 12 / 13 as you will then have what ever is left as a spare. Makes sense in the long run.
