AC vacuum line help

[bcbar8o]

Changed plugs in my 2000 3.8v-6, knocked a few vacuum lines off.
Found where 2 out of the 3 went, but cannot find a home for the 3rd
one??
There are 2 line connecting to a single elbow connector.
Tried looking around with a mirror and flashlight---no luck!
The AC only comes out the defrost vent, and the brake pedal
seems to be lower to the floor!

Any suggestions would be greatly appreciated

Ill take a look at mine..
Ok one red vac line and black vac line run to firewall area. I assume they control AC /heat They go into the passenger side corner of intake plenum. Just to the right of that, a vac line runs from plenum to some where around the coil area. That connection just may be hidden under the plenum some where.
I looked with my cowl on so if your is off it may be easier to see.If not just feel right below where upper and lower intake come together...on the passenger side.. Hope this helps... NOTE!! Mine is a 2001 but should be close to the same...

Mentioning the brakes leads me to think your brake booster is not connected to the vacuum. I believe that line goes from the brake booster to the lower intake manifold.
