Wiring Diagram for fogs on R129

[davidsl500]

Anyone got a wiring schematic for the lighting circuit - especially front fogs and headlamp switch for the R129 ?

My offside front fog is not coming on and the bulb is okay. I am trying to narrow down the problem before getting my hands dirty ! I have a sneaky feeling that it may be the switch itself - does the fog share a relay with the headlamp (which behaves normally. Answers on a postcard please...

I imagine the front fogs are on the same circuit and there will be a wire linking the two. If one is working and the other is not, then the problem won't be far away.

We haven't had any fog yet!

I know that - I'll explain it to the MOT man....

front fogs are NOT part of the MOT...

Thanks Guy, I was working on the assumption that "if its fitted it should work" to be on the safe side.

I cant say that I have ever used them - they dont seem to be up to much anyway..
