I have spent the last few days trying to figure out wiring on my 77 d. Finally in an attempt to simplify it, I wired a completely new harness with LED lights at the directionals. I have a schematic that I used but I think I may have gotten the wrong flasher, the one I have only has a red and black wire and I find no way to hook that up and make it work. Do you , any of you, have an idea of what flasher I should use and how would I install it I am including the schematic that I used. It just shows the Flasher as two wires but mine doesn't work that way.
