65 230 Head Lamp Switch

[LastLife]

Just purchased a 65 230, Swapping out the US AC style headlamps with Euro's, but the fog lamps that are within the headlamp on the either unit do not work when I pull the dash switch out as they are supposed to. New bulbs and when I bypass the switch with direct power they work.  My question is, Is this possibly a bad dash switch (before I order one) or is there something I'm missing?  Thanks, GS

I did the same thing with my '66 230SL; you'll probably find that the relevant wire is not connected to the actual switch.

You're looking for two grey/green wires, should be connected to terminal N on the switch.  There is another terminal N that has a grey/green/yellow which is the 12V+ve from the fuse

which is the 24V+ve

This is the second time in as many days that I've seen someone mention +24V in regards to our cars.  Is there something I don't know?
