0.156" (3.96mm) 6-pin insulation displacement connector (IDC) for 22 gauge wire as used in many makes of pinball machines including Williams, Bally, Stern, Data East, Sega, and more.

Pinball uses mostly 2 gauges of wire.  Most wires are 22 AWG (thinner). GI, solenoid, and high current wiring is usually 18 AWG (thicker).

There are exceptions to this rule.

The easiest way to tell is to compare the thickness of the wires in your backbox to each other.
