Defender 15P solenoid valve question

Evening boys and girls. Newbie here
so please be gentle!
Whilst fitting an EGR delete kit to my 06 TD5 Defender I found what looks like a stray vacuum hose. I traced it back to the two solenoid valves tucked under the right-hand wing. It appears to join the two green vac pipes (one going to each valve) in a sort of double joiner where it becomes a single black hose that looks like it wants to run round the back of the head but it's not connecting to anything.
Can anyone tell me where it should connect up to?
Thanks in advance

I believe both solenoids are for the EGR, they need blanking off (you should have got rubber caps in the kit for this

The solenoid feed connects to the vacuum line running from the vacuum pump in front of the alternator, back to the brake servo pump.
Not only this feed should be disconnected when getting rid of EGR functionality, but for the sake of tidiness both modulators (ILT/EGR) and the related plumbing should be extirpated too.
The tee should be well blanked off (vacuum is used for the braking system!) - I typically use irrigation micro-tubing and a goofy plug (very tight fit). Strictly speaking one should replace the line as a whole with the non-EGR model (straight through) only if it wasn't so ridiculously overpriced! (p/n SQB000300).


This one (pinched from the internet) uses a bung & zip tie to seal the tee off, not my preference but this picture better depicts where the tee lives.


Another shamelessly stolen picture showing all the bits & bobs that can come off (the heat exchanger is a whole different discussion):

Hope this helps.

Ignore - double post

Thanks for the replies folks.
To clarify, I've put the little bungs supplied with the kit on the ports for the two blue hoses that connected to the EGR valve and actuator.
The white tube is still connected to the vacuum line to the brake servo.
I've capped the end of the black pipe that the two green pipes are connected to. What I was more concerned about was where the end of the black pipe should be attached. I'm worried there's something that should be connected that's now open to atmosphere.
I'm pretty sure it doesn't tee into the line to the brake servo because the black pipe is about 18 inches long and it looks like it should run round the back of the head to the exhaust side of the engine.
I'll try and upload a pic of the pipes...

The first pic shows the green pipes connecting into the black pipe. The second one shows the other end of the black pipe (blocked with a bolt). I've pulled it back round to the right hand side of the engine because there are more things to hold it out of the way than on the left side...

My bad Filbee, jumped to my guns without actually paying proper attention to what you were saying. The black rubbery hose connects to the air filter box lid (clean air side), just under/aft of the AAP sensor.
When the EGR system modulators (electrically operated vacuum control valves) are switched off i.e. vacuum is no longer applied to either actuator, the modulators & corresponding control lines are vented to the atmosphere via the line in question. In order to prevent dirt/humidity ingress, "clean" air is drawn from downstream of the air filter. EU3 EGR blanking kits usually include a rubber bung to plug this hole off. Something that has come up before so there must be some specific pictures, though Google isn't of much help today.
Look for the wee (black plastic) nipple sticking out just behind the AAP sensor (where connector C0188 plugs into), it should be sealed off.

Thank you my friend, that solves the mystery completely!
I've located the nipple on the airbox lid behind the AAP sensor. No wonder I missed to find it, it's pretty well hidden...
As I don't have a handy blanking plug at the moment I've just plugged the black hose back over the nipple. I'll get some more plugs and fit one to the airbox and two to the solenoid valves.
At least I know that no unmetered air was being drawn into the intake system.
