I got a hold of a new(to me) bumper for my 75. Cool thing about it was that it had the foglamp areas all ready cut out. So, staying with that cool thought there, I figured I would add lights and wire them in.
In the Haynes manual (page 178 - 185 in my book) it shows that they are called Additional Headlamp(s) (both left and right) in the key on page 182, #21 and 23.
In the previous years in the manual, they are listed as Foglamps(optional).
So my question is, on a 1975, did the fog lights get wired to their own switch on the dash or were they wired to the headlamp switch and just on when the low beam lights were on?
Anyone have any insight to this? It would be greatly appreciated. (calling @JeffBowlsby )
Thanks,
Mike
