Well, here's what I created using the 1971 Factory Service Manual diagram to guide me. I had to carefully pick through about 12 underdash wiring harnesses from various Mopar cars I stripped to get the correct Brown wire with the White tracer with a Female Bullitt end on it. What a pain! I have a small photo of an untouched 71 Charger's washer switch still in the car and that had the unique Red 4 terminal plug (but only uses 2 of the terminals). I duplicated this as well because I believe it to be factory original. Now if I could just see the entire harness from a car to get the correct length and part number on the tag, that would be awesome! I believe I have the harness length pretty darn close on the one I made though. Here's a few pics.
