Where was it plugged?
Is your intake tapped for vacuum?
On my 71 I have a single port manifold with vacuum port. (big port
right below carb)
There is some special hose (wire reinforced so it wont collapse) with a
one way check valve.

the hose goes from the manifold to the servo.

I am not sure that is a valid test, My SVDA dizzy uses vacuum from the
carb.
the booster uses the BIG vacuum port and check valve.

You can tell trust me.
It does not reduce the pedal pressure required to stop a whole bunch,
but it does make it much easier to hold the bus when stopped on a
downhill.
When I took the master cylinder off my booster was full of water and
brake fluid.
H&R in Dallas rebuilt mine in one day for cheap.

It is connected to nothing, it just goes up inside the frame to a void.
