The switch in the dash is to override this when sitting for extended periods on time, like at a stop light, etc. I'd post pics but apparently I'm too much of a noob.
On a side note: add a check valve into the line between the pump and the vacuum switch, as the pump will NOT hold vacuum!

Thanks for insight, but I am getting rid of my vacuum boosted brakes and going with manual. I have machined plates for the current ratio which is 4+:1. I have a plate for 6:1 on the nose, but it won't work. I can do 5:1, so I am working on that plate now as well as a mod'd brake pedal arm.
Right now, I did a trial run with the OEM spec ratio but without the vaccum booster. I was pleasantly surprised. I can say it was actually better braking than my prior MB W123. I think the 5:1 ratio will actually out perform the current vacuum boosted brakes. So, I only need a little vaccum, e.g., 4 door pods, trunk and fuel lock, IP, ignition, and HVAC pod (I have manual HVAC controls).
Do you recall what you set your vacuum at ? I think a lot of those switches are adjustable. I will have a light bulb in my cluster which will go on when the pump is running and I will have have a on-off switch to kill the pump if the pump runs more than 15 seconds for example. If you remember, please let me know.
