it should be but hard to say where!
if you cant find where it plugs into then plug the pipe with a bolt as it will booger up your running otherwise.
it will or should go to either the:
fpr
carbon canister
boost gauge solenoid on n/s inner wing (little black box)
check all T connections to make sure its not come off one of those
edited as ive just seen its coming off your dv
it will either go to a T piece somewhere or come directly from under the inlet plenum to a vacuum junction box.
your dv will not work unless this is plumbed in correctly

+1 That's the vacuum/boost line that pulls on the diaphragm in your dump valve to open it and release the boost. - Because of the design of the HKS unit (reverse diaphragm) it won't open unless that's attached; the boost actually holds it closed (which is why they are good for high boost applications; there's no spring creep).
Incidentally, that means that the screw you can see DOES NOT adjust the noise or boost pressure (or any other story you may have been told); it's just for adjusting the vacuum required to open the valve, so that if your car has very high vacuum idle it shuts and doesn't let unmetered air in. I read an article by someone from HKS who said that he wished they'd never put it on there because nobody reads the manual, then they fiddle with it and break the unit.

That's the odd thing. It chatters away quite nicely.
Should it not with that pipe unattached?

To be fair, mine aint got anything on that pipe, and I have the same bov. Seems to work on mine. Got me worried now!! :lol: :roll:

I'm sure it's nothing to worry about fella.
Because i'm not terribly switched on with whats what and what goes where, I get a bit nervous when I see something blanked off.
Sometimes I feel like I want to take the whole car a part, just so I know how the flippin' thing works lol.

Funny you should mention the idle, 'cause it does have a slight idle issue.

I plumbed it up on Friday and all seems well.
The BOV noise when dumping has changed.
Before it was a constant chatter.
Under light load it still has the chatter, but under heavy load it's now got a definate tsssshhhhhh with a faint chatter underneath.
Had a quick look on HKS website, it says that the SSQV dumps light and heavy loads differently so I guess it's as it should be now.
Thanks for the help chappies.
