I was wondering if anyone could help me. I was going to mod (ie fix) my old starter pair of ATH M30's for my nephew. Had one of these lying around: http://i47.tinypic.com/2z6ca2o.jpg and figured id fix up this old pair for him for the time being. My question is which cable is the ground and which is left and right. See photo: http://i45.tinypic.com/2v0mp2q.jpg also which is post left and right post on the mount jack. Thanks for any help you can give.
