Unknown vacuum line help

Does anyone know where this line attaches to? 1998 3.4l v6. lost all the videos on my phone showing me where the vacuum lines are supposed to go.

 

Take a look at the underside of your hood
Should be a vacuum label

lemme research real fast…..

 

That's your Idle Air Control (IAC). I can't find any pictures in my phone of where that goes to for my year. It's labeled as the Air Assist Hose in the FSM, but I can't find a better mention of it.

1st Gen 3.4 Vacuum Hose Thread

Thats a link to a thread on here... Kinda what I thought. It's pretty buried- but goes down to the intake manifold. The Y and the two legs are really only accessible when you have the upper intake manifold / plenum off.

 

pix is your TB^^^

On mine(96 2RZ however)

the large hose inlet goes to intake tube
The 2 smaller inlets(well inlet/outlet if I’m guessing correctly)are for coolant fed through TB. Both these are same size too

 

Went through the vacuum hose forum and found the right hose and connection

Thanks

 

The other approach is find one of the hoses that reaches it.
