Vacuum port on 3rz intake for ps pump

I have a non threaded hole on my 99 intake presumably where the vacuum line for the power steering pressure valve should go. Any idea what the fitting looks like?
I could plug it but what are my options there as well?

 

here's a '98....




That steering switch just taps into the vacuum anywhere on each side of the butterfly.....

 

Thanks!
What does that fitting look like? That port on my intake is not threaded.

 

I think there is like 2 or 3 different plugs/holes there...

the newer with electronic switch just plug those....

your talking about 8psi.....so not much.....to seal it...


I've got that upper plenum I pulled off an old 4 banger taco 5 years ago...
tomorrow I'll go look thru the junk pile and see if I can find that....

 

Well I looked at mine....and that tube appears to be pressed in....

There's a plug below that I've seen others use.





IF so the high one should be easy to plug since it only a few lbs of vacuum..

and find something to thread in the lower....

 

Appreciate it!
