Looking for help with my GI relay board area, underside of the playfield back right. My GI was out or partially out and I was blowing fuses. Found this board hanging with previously burned connector/header inerface and wires soldered directly to the underside of the board. I am replacing it (replacement in hand, mounted) as it seems a good place to start.
What I have now are 4 wires, 2 purple and 2 yellow. I cant tell what goes where, though I have a photo showing the YP_YP sequence. I just cant tell the two purples or 2 yellows apart.
It appears I have 1 purple and yellow that connect to the underside of the playfied, and 1P 1Y that make their way up into the backbox through the massive mess of wires. Anyway someone can take a look and tell me which feeds to which pin on their machine? Thanks.20200428_155228 (resized).jpg
