Independent Fog lights
 

How can I get the fog light to turn on without turning on my headlights on my 1983 W126 300sd??

Pull the knob out and turn to first click position.

You have to put a jumper wire on the headlight switch to do that.

In some states that is illegal

Try a search, maybe in the diesel section. Someone did it by moving the fog light wire inside the fuse panel. Disconnect the battery first! If I recall it involved moving the orange wire? (fog lights) from the headlight fuse (#13?) to the running/turnsignal fuse (#6?) Check a wiring diagram as I'm not sure about the color of the wire or the fuse numbers while sitting at the computer.

Yes, hitwtom , I know. That's the exact information I was looking for. I searched and searched for a few days with no luck here. I found one guy that did it to a W123 by searching google, but I am not sure if my car,a 1983 300sd, shares the procedure. Before I go tearing into my fuse box, I want to make sure I have all the correct info.

so any other thoughts about this?
