Ok I was going to respond to you originally where I found most the wires but couldn't find the double white on the far right, scratch that, it was tangled up in the bundle between the factory zip ties (grr.)
Anyway I took what people said here, but figured I'd throw caution into the wind and went for it. I touched the various sheer off loops to their proper spots, and I found out the switch worked on the left. At first the right one had me thrown as it was looking like it was scrolling fast spazzing out, but then it wasn't (probably my hand shaking.) I figured what the hell, heated up the soldering iron which I'll admit I'm not that steady/good with, and started fusing the old solder (and a little bit of new) into the right spots, double green, white diode end, then white wire end(left). Tested, worked, it sucked all the scores out of the game. Then went for it on the right, got the white on with less struggle than the others, and boom, test options now work too. My system is restored thanks to your generously clean image of your switch/wiring layout.
I can only imagine what kind of boobery was involved in mashing up against that or raking it with the coin trough to snap those off but it was NOT broken and shouldn't have been detached.
Also interesting, supposedly the 1P spot has 111 plays on it registered, that is IT. 2-4 have like 1-4 plays. There's no way this thing could have been that little played even under home use.
I just now need to figure out how to mess with the settings, couldn't figure out what to push to cycle features in the setup area. Also what's all that about on the apron about hold flipper for 4 seconds to see status report?
