Default Small black nylon line around PCM

Where does the bottom of the "T" run to? Apparently mice have chewed my line in two and I can't find/figure out where or what it goes to.

Can anybody trace it out for me and see where it goes? One side goes to the back of the intake manifold and the other side goes into the harness going over the passenger side fender, but where does the bottom go?

iirc it goes to a small vacuum tank under the front of the car that stores vacuum for the a/c system so when you get on the gas the lack of vacuum for the a/c system doesnt make the air blow onto the floor

I am pretty sure that's the other side of the "T" that goes to the front. That one is intact, I need to know about the bottom. Thanks though!

the other side of "T" on the back of the intake goes to theA.I.R. solinoid if that is deleted then you need to cap it because you have a vacuum leak. i deleted my a.i.r. and removed the "t" just plugged existing line back in. its abitch to get to. i've used amirror and flash light to make observations easier.hope this helps..

One of those lines from the T connector goes to a port on the back of the intake. A different line goes from that port on the back of the intake to the AIR thing (I think it's called a vacuum modulator), on the driver's side.

Trace your line from the back of the intake to the vac check valve (t-fitting).. From the valve, one line goes through the hvac box on the pass side firewall into the cabin for your ac/htr control.. The other goes to your vacum resevoir towards the front pass side fender.
