If I'm orienting myself correctly, you want to look towards the center of the car, as you're on the left side. Follow the large ribbed hose in the lower left of both pictures to wherever it goes off the side of the picture, that should be your throttle body, and it should have some small rubber lines coming out of it.
The intake box won't have any vacuum lines going into it, as there's no (significant) vacuum there.

That big hunk 'o' plastic on the front of your engine is your intake manifold. Where all those runners come together is your throttle body. I don't believe you have a plenum on your Neon, so try to find a vacuum line coming from the throttle body and tee off it.
All the lines are no more than 3mm ID.

You might try posting to a Neon list. No doubt those guys know that engine compartment in their sleep. I'm not seeing any visible ones, so they're hiding under something. |

I know this is old, but it was not fully addressed. Your tach shows how fast the engine is turning, not how hard it is working. Let's say that your engine turns at 2,000 RPM at 50 MPH in 5th gear (for the sake of argument). Going down a hill at 50 MPH, it is turning 2k RPM... on level ground at 50 MPH it is turning 2k RPM... going up a mountain at 50 MPH it is turning 2k RPM. Those three scenarios would see a very different load on the engine, and a very different amount of fuel being used.
A generator is a good example. Most gensets run at a single speed. The more electricity you use, the more load on the engine. The more load, the more fuel is burned. Same speed, different amount of fuel burned.

...a TACH tells you how FAST the engine in BREATHING.
...a VACUUM gauge tells you how DEEPLY (or not) the engine is BREATHING.
...in other words, a tachometer is a "rate" measurement device (rev-per-minute) while a vacuum gauge is a "differential" air pressure measurement device, ie: air (29.92 inches-Hg) vs. vacuum (no air)...basically, "how deeply" the engine is trying to intake/breath air.
...at wide-open-throttle (WOT), the vacuum gauge will read nearly ZERO inches of vacuum (very little difference in air pressures), but at idle will be somewhere near 20-22"Hg (67-75% of full vacuum).
...the amount of "throttle" restriction, engine RPM, and engine load determine the vacuum gauge numbers.
