Fun-Fest was my first project pin. I had an issue with that roll-over switch/wire also, I found that the wire was actually on the wrong side of the switch underneath, once I corrected that I need to adjust that roll-over wire, it was bent down too far so when the ball would roll over the wire it would not make full contact with the switch underneath the pf. I also attached photos of the relay and schem. if others want to take a peek.
thanks
