Ok, I've been looking at this vacuum diagram for the European light vacuum adjusters.

Now, being a diesel, I don't think that layout will work, it looks like it was drawn for a gasser with the extra reservoir in the fender, which to my knowledge, diesels do not have. So, my question to you all who have Euros with vacuum leveling, how did you go about finding a source of vacuum, and how did you set yours up? I did a search and this topic has not been discussed as often as other issues.

Looking forward to your feedback.

Hello,

it is an easy, straightforward procedure. Connect each of the lights to one vacuum line. Remove the instrument cluster to pull and route the lines inside. On the vacuum adjuster there are 3 prongs. The outter prongs connect to the lights, the middle one is for vacuum source. It doesn't matter which light connects to which outter prong. Connect the light lines to the adjuster, connect the middle prong to an additional vacuum line and route it back just above the brake booster. Use a rubber T connector and tap any vacuum source. That is it.

The above procedure only applies to the late style 124 switch which has three ports and an integrated check valve. The early switch has only two ports and no internal check valve. Htownbenzo, follow the diagram that you posted but use a single port check valve and run it directly to vacuum by tee'ing into the brown line at the main vacuum line.

Did you just win these......
