I am working on an Amazing Spider Man restoration. Why would someone create this hack connection between the power supply and driver board? Also note, the unattached red/white colored wire. If I disconnect the hack, I cannot tell any difference in starting a game - boots to attract mode, game will start. I do have some switches not registering that I need to track down.

Thanks

There is also an red/orange wire coming off one the top saucer gi lights That is not connected to anything. Have no idea what that is.
