Which vacuum tubes go where on the wiper door vacuum switch (the one that contacts the wiper arm)? There is one line for vent, one for vacuum source and one that goes to the vacuum relay valve.

I realize vacuum tubes are antiquated tech, but I remember them well....
it wasn't untill what?? '68 or so that flower transistors.....named Germaniums came into being....thing that did them in as they tended to grow crystaline structures over time and use....
I knew a good broad once, what was a good vacuum switch...
other than that....the vacuum relay has a source and TWO putputs from that larger source line...the diaphram is loaded by a spring and so the presence on the suction side of engine vacuum pulls the valve to one position...and absence does the opposite....
there is a vacuum valve///one way action in there...coming off the main vacuum source..the manifold...
see several threads for the operational details....

According to the drawing I have downloaded,
1. The line off the top of the switch, green, is the vent.
2. The middle line off the switch, red, goes the the upper point on the pull down switch under the steering column.
3. The top lind off the switch, white, goes the the control port on the wiper door actuator relay(the metal lid port).
