Hello. I just inherited a Williams Fire! pinball machine. It has a system 11A board set. I have one 2 pin molex connector at the back of the machine which I can not find where it connects to the large wire harness connected to the play field.

I can tell you that the wires going into the 2 pin molex connector appear to be:

1 Gray (with candy cane yellow stripe)
1 Black (with candy cane yellow stripe)

It doesn't help that I can't read Williams wire coding correctly.

On the schematic, the gray wire look like it is connected to the flipper power supply. I don't know if that will help or not. Please write me if you even have a clue. I know I don't.

Thank you,
Bill

Do you have a manual or schematic? I think that connector is J16, on the left side of the interconnect board.
