W107 diagrams
 

All:
I am trying to de-bug a recently acquired 1982 W107 I bought to keep my '65 W113 and '63 W198 company. I have numerous HVAC and cruise control problems that are most likely vacuum related. Also acting up are the blower motor and power antenna so I will be tracking down electrical glitcjhes as well.
Can anyone point me to an electrical schematic and/or a vacuum diagram posted on the internet?
Much Thanks in advance.
