New wiring for our ‘67 B’cuda

The previous owner would have embarrassed the guys on Roadkill. Due to the number or cut wires, spliced in wires, disconnected wires and the general lack of color coding, I purchased new harnesses from M&H Electric Fabricators. Expensive, but damn nice… except …
Why can’t they label their wires? I labeled everything I could when I took the old one out, but the Junkyard Warriors had already worked their magic. I can read a schematic and eventually I will figure it out, but it sure would easier if M&H would label their wires.

OEM wasn't labelled. Exact reproduction of that wouldn't be labelled. Factory harnesses have many different connectors and just barely enough wire length so their line workers couldn't get it wrong.
