2phast,

Did you ever hook up the vacuum adjust?

On my w123 the right side is vacuum, the left side is no vacuum adjust. I wonder if all of them were like that because I was looking at some other cars, and they have one light hella left, and one light bosch right...Im confused.

Where do you grab the vacuum for the switch?

Anyone have the part number for the vacuum headlight switch (rosetta dial)?
