I had a link somewhere for a diagram of the vac syst in my 1981 300TD wagon (mainly door locks and control panel needed for now - so I can bypass them and shift better till the transmission angels grace me) but I can't find it. I can only find ones for 1982 and later. I think there are differences. I would love some help.
