JCW Intake Vacuum Line

JCW Intake Vacuum Line
I'm trying to reinstall the OEM intake from my 05 JCW and the vacuum line was capped off. I've picked up some new vacuum line and and attempting to reroute it to the intake (post installation). I see a small tube at the front-left and more at the rear.
I've googled to no avail. Anyone point me in the right direction? I could do trial/error but I would rather not pull the airbox unless I know I need to.

Here are the instructions from MINI. Hopefully they help.

Should be a hard plastic line out the front of the box, it will lead internally to the diaphragm which operates the flapper....

The vacuum line at the rear seems to be already connected to something else.. I didn't have much tinkering time this evening after getting the kids to bed, will take the airbox out tomorrow.
I did have time to hook the vacuum line to the hard plastic port at the front. The flaps opened at 4500 RPM.. then I recapped the line and shot a second video confirming that the flaps opened with NO vacuum lines at all. What impact would vacuum have? Airflow sensors?

Confirmed, vacuum has no effect on flaps. It's entirely controlled electronically. The vacuum line at the front of the air box is the correct line. There are only 2 wires going into the air box, presumably +/-. Shouldn't be super complicated to run power to the lead wire and connect a button to turn on/off at will.

Returning to this thread to update on my vacuum lines.
I tried jerry rigging some new, larger vacuum line (actually it was small irrigation tube I had but that's a longer story), the original remnants and heat shrink. It was a great idea that worked well until the plastic elbow fittings started breaking on me. All 3 of them. Went to Advance Auto (is that a crap store? Which is the best out of them, Oreilly's and Autozone?) Anyway, 3 staff members had no clue what vacuum line is and a kid that worked there knew where to find it in the store, which is what mattered really. I ended up buy some different sized hoses and some elbow fittings hoping they'd work. I don't suppose anyone has part numbers for the vac line and elbows?
So I go home, mess around and get it hooked up, thanks so much to RB-Mini for the picture. Took it for a drive and I dunno, but I don't think this Mini has ever driven so hard. And the SC whine was unbelievable. Did some perished vac line really affect performance that much or am I delusional?
The point of this post is you can likely find parts to replace your lines at the auto store, and the performance in my opinion, after repair, was out of this world.
Also, to ask for part numbers if possible, of the line and elbows.
TIA

As the flap actuating system is tapped to an existing vacuum line on the motor, wouldn't a vacuum leak from a bad airbox hose have some type of negative effect on performance or drivability? Not sure how big of an issue it could cause, but I was under the impression it wasn’t good when there’s a vacuum leak.
