Since the ignition switch and headlight switch are fairly inexpensive, I suggest replacing both at the same time. Lastly, the wiring harness in the 1969 Mustang is of it's own unique design and layout (meaning it does not interchange with the 1970 Mustang), as is a good majority of the 1969 Mustang as a whole (mechanically speaking), going to a Mustang parts house instead of the local auto parts store will net you a better replacement piece. Once again, just my advice based on 30+ years of working on these specific

i agree with the ign wiring being the main power and the same wires that runs the alt. runs other stuff. the other stuff works ok. ???????????????????? and if yrs got anything to do with it i got you by about 15.
