from memory it goes to the charcoal canister if it has one, you can pretty much block it off, its not really needed unless the car is not doing to well with out it

so far i have been playing with it and from what i can tell it controls some sort of throttle advance because it moves a diafram on the throttle body and when you block it of the revs drop down to 700ish rpm

If I am correct you are talking about the PCV hose. This should run down through a tab on the intake manifold pipes, where the PCV valve is located, and then run down to the breather box on the back of the block

ok i think i no the box your talking about is it located about mid way on the block and is reasonabley large

Any vac hose on that side of the throttle blade will affect idle when blocked and unblocked. As it's an air leak when unblocked.
