Nice !! With a little research you are now qualified as a Ford electrical technician...Lol Isn't it great the way things were so simple back in '77 ?? The whole fuse box holds maybe 10 fuses, not like todays rides with 30 or more. I miss the old days !!
My 77 has the turn signal flasher unit glued to the fire wall, 4" from the headlight switch behind the gauge cluster. I would have never found it without taking out the panel and unhooking the left AC vent it was behind. There is no way to reach it other wise.
Hey the video is great. Straight forward and informative! I have a 79 step side I'm struggling with right now. Where did you find the wiring diagram? Is it possible if you could please send me a digital copy? I have head, turn and running lights. No brakes or hazard. The break switch is good.
