I have a low vacumee switch under my desk (I'll probably never get it hooked up) But it is in my plans.

Only one of the five vacuum-trailer-brake controls that I have has a simple screw-in 1/8NPT low-vacuum switch, TEEed into the gauge port; the others only have the line to the gauge.

If I could come up with more of these, I would simply hook one of them into the truck vacuum and the other into the trailer vacuum.

The best I remember, it has Stewart Warner stamped on it.

Anyone know where I can get these ??

Thanks.
