I had to replace the head on my 03 Corolla and after putting it back together I ended up with a free vacuum hose that I am trying to hook up. Picture here:

From this photo I am pretty sure the S shaped tube shown here:

is the same as my tube and I do have an open nipple located on the intake manifold that is not attached to anything. The problem is I cannot see where the other end attaches to. It appears that whatever it did attach to broke off while removing the head/manifold etc.
Would someone please tell me / show me where the other end attaches to?

Any help would be appreciated.
Thanks,
James

There should be 2 coolant hoses on throttle body. Nipple on intake manifold behind throttle body goes to brake booster.

Thanks! That was it, My brother-in-law had the brake booster hooked up to the throttle body coolant port. One of the coolant hoses from the throttle body hooks up to a valve attached to the head right?

The shorter throttle body coolant hose with a sharper angle is fitted to the metal tubing section of the "Water By–pass Pipe No. 1".

Ok. I am still having problems finding out where the other throttle body coolant hose goes. I suspect that it needs to plug into a port on the head of the engine. I am unable to see exactly where it might go.

I think i might be where this plug is located on the head. It is possible that when I had the head milled and pressure tested the plugged up the port with this plug:

Here is a closeup:

Any help on this would be appreciated.

Can you see this part with both hoses on it:

The same part labelled 16268 as shown in the figure you posted above?
i.e. http://jp-carparts.com/images/parts/163110/163110_1603_0005.png

I know that one of the coolant hoses connects to the water bypass pipe, but I am unsure as to where to connect the other (return) throttle body coolant hose. Any ideas?

Thanks,
James

Fill cooling system with water, and see where it comes out.
