I found these extra connectors in the cabinet. What are there? What do they do? Nobody knows. One has black & white wires. One has grey-white and grey-brown.
Extra connector with black and white wires I found wrapped around the wire bundle leading to the front (left flipper, start button, coin door)
Close up on the connector. I think these wires are coming directly from the power input box.
Extra connector with grey-white and grey-brown wires by the kicker and flipper board
Close up on the connector. I think these these wires run to the back box, but they’re bundled with a bunch of other wires so it’s hard to see for sure.
Update: mystery solved! These are for a bill validator so the game can accept folding money. Thanks to vec-tor at pinside.com!
Update 2: I put the meter on the black & white and got +10.5 VDC, Could come in handy if I ever add additional playfield lighting or other gadgets.
