Vintage Cars: !974 W115, fog lights, w114

Question
Hi Ron,
Do you know how to turn on the fog rear light on this car
and I think the front seats are heated or at least there is
a cable going to them, if they are heated how do you turn
them on?
Finally I want to buy the round fog lights but I had no
luck locating them.
Any points?
Thank you very much.

Answer
the rear fogs turn on by pulling out on the light switch, not all cars had the connections hooked up, cars to the US typically did not.
Its not a bad job to hook them up , but it does involve a lot of rewireing
I am not aware of heated seats in the 74 W114 or W115.  Most likely the wire you see is a seat belt indicator/warning system. Front fogs for these guys come up on ebay from time to tiem, or just keep an eye out for them in the junkyards.  I know of a set, if you are interested I will see what the guy wants for them
Good Luck
Ron
