Autometer vacuum gauge hook up Question

[chevyaz]

I got a new Autometer vacuum gauge and was looking for some help on where to T off to hook up the vacuum line. Could i use any emmissions vacuum line, map sensor? These dash gauges are confusing sometimes. I have a 1994 gmc truck 350-5.7. thanks for any help.

You can T it off any vacuum line that has constant vacuum from engine.
