The YearOne harness looked pretty good in my opinion, but I wrapped mine in friction tape to make it look a little better and to clean it up a little.

As you can see I added an ECU bracket which is typical in later years and I tried to use a double ballast where the single used to go. It does not fit as well as I would like but I haven't found a way I like better yet.

I did not choose the double-ballast but when I ordered the '70 Cuda engine harness for a 440 and Electronic ignition, this is what they sent me. I can post any photo you want of the harness and its connections. I did make some modifications for electric choke, horn wiring and MAD bypass wire but with a little friction tape it all looks factory.
