Bought a couple of Mark C's coin doors and was aware of possibly replacing a plug. I'm just wondering what that small plug currently on the door is for?

Why am I interested? Well on my TZ it has only one plug going to the PCB and an earth wire...that's it. I remember someone asking once why his door interlock doesn't work on his TZ (mine doesn't either) and I'm wondering if this has something to do with it???

The coin door PCB is the same on all my WPC95's so would be keen to know the answer before installing without the plug
Thanks

Rob,

The small plug I understand is for P2K games.  It simply is a plug which goes into the coin door interface board for the coin mechs, power to the coin door lights and for the diagnostic switches...

My thread on the one I did is here:  http://aussiepinball.com/index.php?topic=2295.0
