Following this intently over here boss. Does it use the flipper relay on the old driver board? In your last pic are ORG and GRN wires, those are supplying Ground to the flips. But I don't see the other two on the connector below. Both sets are feeding or fed to the relay to enable the flips. don't know which set that is though, before or after the relay. Doing the same thing I showed you on my project. it looks like the other is plugged onto new board in the first pic
