This is how S4 headlights should behave. When you add them to a 100 the low beams turn off when you turn on the brights.

There is a wire in position 8 (green arrow). Take this wire out, you will not need it. Then take the yellow wire from position 7 (aqua arrow) and relocate it to position 8.

If you have stock 100 headlights this should not concern you. It is only for the few of us who have upgraded to urS4 headlights.

Thanks to Brdman* for figuring this out on his 90, the wiring is the same for the C4.

I actually got all the info from the UK S2 forums.

Brdman, does yours still work? I'll have to take a look at my wiring diagrams...

Brdman*

the wiring diagrams do mention it's for the fogs though.

What does pin 1 do? I don't have anything hooked to it and it isn't in my wiring diagrams.

Thanks...I'll do this asap!

They are supposed to act that way.

When you install them in a 100, the lows turn off with the highs without this mod.

Bmthorn

Yep, this is only relevent to those who have put s4 headlights on a 100.

So your rear fog stopped working after this Brant?
