The wiring harness that was sold to me came in one piece with 2 white, 2 green, 2 purple, 2 gray, 1 black, 1 grey, 1 yellow. I asked about it since I bought the harness to install my old radio in Brad's car at the same time which was in 2 pieces (also has Mach 460) ... He said that it had changed and I this is what I would need, but I would need to adapt it to make the 460 work.
