Wiring EVH one nob

I am based in Germany and my Guitar is in for repair. The guy who is doing the work has asked me if I can find wiring info or photos for an early nineties MusicMan EVH with one nob. If anyone could help I would be very grateful.
The treble pickup also needs rewinding, so I could also use info on make, model and power output. I believe the pickups are Dimarzio? Thanks
