Where is map sensor line

I am instlling guages on my 1996 Ford F350 power stroke. I am not sure where the map sensor line is at. I tap into a short vacuum line from the vacuum pump but the boost guage does not seem to work.

I don't have a picture in front of me...but it is a line that goes from the base of the turbo over to the map sensor which is on the passenger side of the engine compartment. I'll see if I can find a picture.

On edit...take a look at this thread. In the one picture you can see it labeled on the left.

I have tapped into the map line but my boost gauge will not work. We tested the gauge and it works fine but the gauge wont show any boost while on the truck. Can somebody give me some help?

Is this while standing still in the driveway...or on the road under a load or WOT conditions?

The gauge will not move at all going down the road. I checked all connections and they are all hooked up correctly.

you can see where I taped mine in the map sensor hose here.
it is the black hose on the left hand side of the picture with the white T and small white hose (my boost gauge hose) coming out of it.

My guess is you tapped it into the wrong line.

why would you tap into the map senor line? wouldn't it be better to drill and tap into the y-pipe. the boost gauge should come with a threaded fitting to do that. thats what i did with my factory y-pipe.
