I have a newer harness for the Mopar electronic dist, it's plug and play, different ballast, voltage reg and square back alt. It's off a newer DART. The picture that your hand is in, you were holding the alt wires. Down on the floor to the right, two eyelets, coil, I think. Mine is blue pos, blk/yel tracer neg. My '69 sm is saying blk pos, gy neg for coil. I don't know anything about your MSD.
