Wife bought a 03 cobra with a Mach 1000 system that had the subs and amps removed but still worked except the cd changer. purchased a used head off ebay, advertised as working perfectly, and the same problem... There are a few wires in the harness where it plugs into the back of the head unit that are not part of the two plugs, just floating free. Are these related to my problem, or did we just get screwed (twice)?
