So there is another! Thanks. I put mine back in place but did update to led flasher and polarity switch plug.I just discovered the same inline fuse to the turn signal flasher on my original dash harness ('70 Super Bee). Seemingly the same uniquely looking fuse holder as in your picture. I have had the car since the mid-80s so I know that LED bulbs do not play into the picture. I plan to move it over to my new M&H harness just because.
Oh, and the flasher is factory original, correct date code, so I am guessing that the pigtail is also factory original.
