Which Vaccum pressure line to splice?

Yes, I have done a search and found nothing. I am trying to find the right vaccum pressue line to splice into, to install a vaccum pressure gauge. I have a 99 Sprot, 4.0 inline 6. Can some please point me in the right direction. Thanks
 
Any line off the intake manifold. Look around, My 96 has a plugged port on the manifold in front of the throttle body, that would be a great place for a vac gauge hook up.
 
Tap into the MAP sensor line, since that's the one the ECU uses to determine engine load anyhow.

Alternatively, there should be a vacuum "tree" somewhere on the intake that is used as a source for various vacuum control signals (but I'd rather use the MAP line anyhow.)
