Does anyone have a schematic of the multiwire Gray harness comming out of the back of a matrix pachinko? The one I have has volume controls wired into this harness. I usually hook up my volume controls at the individual speakers. The volume controls on my machine (5 of them) full blast is only about medium volume at best...I wanted to double check to make sure something was not wired correctly because all of my other machines with volume controls will go from quiet to full blast.

Thanks
