I have the same wire colors as joeschall. I connected yellow/green to green (ground), which goes to the transformer, blue to brown (neutral), which also goes to the transformer, and then brown to yellow (hot), which goes to the fuse holder. The game has GI and works, but there is a loud buzzing that I don't remember hearing before. Using the wooden chopstick trick, I found that the buzzing is coming from the lock relay. Is it possible that the game now has plenty of juice and the crispy lock relay is just struggling to stay on? I think I'll search for "buzzing relays" next.
