Thanks in advance for the great threads I have seen so far.

I have put over 2000 buck in my 82 240d in less than a year of buying. I have made the choice to start taking matters into my own hands.

My question is this: How does the vacuum switch on the ignition work? I have to be to work on Tuesday and need to rig my car to run, I am a delivery driver. I know what is wrong and am going to order the part and I know how to work the electrical end.

My guess is this that I take the working vacuum switch and hook it up as normal. I believe I have diagrams for that. But you can move the piston to an in or out position. I believe that the vaccum has to be closed (depressed valve) in order to make the car run. Then all I have to do is unpress the valve when I shut off the key and it will stop??????If you have any idea what I am talking about please help, and thanks again.
