Hi , i have the same problem . I think i put one wire in the wrong spot and now i have scoring issue . Can you post a better picture of the wiring so I can see where I went wrong . Nobody answered my post either . Maybe together we can figure it out . Tks

Just fixed mine , pretty simple ( after checking pics ) . Two wires per contact , one wire to the two spring loaded contact the other wire to the two sleeves of the spring loaded contact . And one contact goes to ground , one wire from sleeve one wire from spring loaded contact . So the one that is missing a wire either on sleeve or spring that's where it goes . Just hope I didn't make this more confusing .
