I thought I'd share the location of the American Autowire harnesses
these are simplified thru graphics as apposed to just line diagrams.
I'm not sure they follow the exact color code for the wires so follow at your own risk, I bought the hardness for my 65ss and everything checked out fine. you can do a search for your (year) wiring at this location
To my knowledge AAW uses the factory color code on insulation and the striping.
We do use most all of the correct factory coloring, however, these instructions are for our Classic update stuff, not OE stuff, and there are very many differences. I would not consider using our Classic update stuff to troubleshoot a factory style-wired car. We update the designs and make them more efficient, so in many instances, stuff is not routed the same, wire size and color can be different, etc.
