[W126 Coupe] Vacuum Diagram -

[MS. J]

First off I hope everyone had a nice turkey day.  I spend some of my vacation days changing filters, and trying to find out why my car has lost a lot of its power.  I got a good look at a lot of the wiring and noticed that my vacuum lines were not attached in 3 places.  One I fixed but the other two have puzzled me some.  
   
  In the front drivers side, right behind the headlight,  there is a purple/black vacuum line that got disconnected from a vacuum valve that is attached to the fender.  Not sure what that valve is for.  
   
  The second disconnected vacuum line looks like it is coming from the transmission or maybe the rear of the engine.  It is bundled with some other wires at the back firewall but not sure where the other end of this line goes.  I am thinking that maybe this is the reason my car is putting and has a low idle and sometimes shuts off. I am going to take the air filter off and see if something is not connected around the fuel pump area. 
   
  So, if anyone out there has a vacuum diagram for 1987 560 SEC, can you send me a link or paper copy, I would greatly appreciate it.  (fax 8182477223)
