Where does this hose go on my 1995 Toyota Tacoma?

Engine struggling to run unless I cover hose with finger, where does it fit?

 

I can look tomorrow, that's what I have is a 4cyl 95.

Thank you!

 

Mine goes to the VSV to the left of your hand that's on top of the valve cover,, it has a couple of wires that goes to the valve, this valve idles up the engine when the compressor comes on and idles back down when it turns off, clutch dis engages. My valve was a little brittle and I broke it off trying to take the hose off or put it back on, can't remember it's been to long. I was able to zip tie the valve back together because of the expense of it. Works great and has for 5 or 6 yrs, but you'll have a bad vacuum leak as you found out.
Mine is 4 wd the truck in the video the guy is working on is 2wd, and I didn't see a VSV on his, you don't state what your's is.

I suck at trying to post pics, I'll try some more later, gotta run for now, if you need them.
