Get a portable vacuum pump with a gauge. Take the vacuum hoses off one at a time apply a vacuum to them, and turn off the pump. Or just use a hand pump.. The hose going to the leak will lose vacuum.

Ron's answer is good. I personally use a propane torch (not lit of course) or starter fluid. Either will cause a marked increase in the engine rpm. That narrows the search considerably, especially when you consider vacuum is used to do everything but open the trunk lid. Oops, I spoke too soon.
Now let's not be stupid, no smoking or open flames and I wouldn't spray starter fluid on a hot exhaust system either. Just be careful and act like you have some common sense and you will be fine.

get a water bottle and lightly mist around the hoses with the car running when the car smooths out you found at least the area of the leak.

Do you mean in the cab? If so its probable your vent control box. Engine vacuum controls the flaps the divert the air for the defrost vent to the floor and regular vents.

Carb cleaner works good. Spray it around and when the car picks up rpm be looking in that area.
