I've replaced 2 complete harnesses in 66 conv's and am going to replace the one in the coupe this spring. The NPD harnesses were very correctly color coded to the wire diagram. The harness I just gor from restoremustangs.com looks like a different story. If some of the wires were not obvious you could probably not trace them from a diagram.
Good luck on your endevor.
