Managed to track down a picture of the wiring 
Great news.
Is it a keeper ? I love my Bally EMs and there were plenty of these made for the Euro market. I think the artwork is very cool for this era.
Yeah Nino it's a keeper. Playfield has some wear but everything is so clean. I'm really surprised as to how clean this machine is.
I'm going to repair the playfield and enjoying looking and playing this beautiful EM. When it's all done I'll post some pictures of this one.
