Can't figure out where my hoses go (N/A S4)

I labeled about everything I couldn, but in the rush of the swap, not everything made the tagging department and/or the tag fell off or became unreadable from grime. So I'm left with a few hoses and connectors I have no idea what to do with. I also couldn't make any sense of the diagrams I dug up by searching.

No idea where this vacuum hose connects.


Can't find where this one goes either.


2 things in this picture. I believe the large hose that goes to the thing on the right connect to something of roughly the same diameter towards the bottom left, is this right? Also, where does the loose connector go?


No idea what this is for.


Not sure about this connector. Coolant level sensor maybe? Yes, I'll be electrical taping it so the wire is no longer exposed. Wasn't hooked up when I got the car.


No idea on these connectors. They weren't hooked up when I got the car.


The large diameter pipe in this picture on the dynamic chamber (not the small vacuum hose).


Large diameter hose with no hose clamp. Was not attached when I got the car.


Not sure if the little nub thing at the center of the photo should be connected to anything.

the single nipple on the uim where it mees the lim goes to the boost/pressure sensor on that side of the engine bay.
the two flat connectors in the front go to the horns iirc, just look for something with a flat spae sticking out.

the big hose with no clamp usually has a pipe running to it from the midpipe, to open the 6ports with backpressure. it looks like your missing the pipe and the 5th and 6th port actuators themselves.

Thanks, I'll check those out tomorrow.

I removed the actuators because one doesn't work at all, and all the equipment to activate them was missing so I figured that I'd remove both actuators to get rid of some deadweight clutter. I also removed the intake sleeves so I'll be down on torque but my top end wil still be up to stock power. If I get bored, I may work on rigging up an electric motor that moves the sleeves manually.

Sweet. I pulled my system when I took the original motor out. But those weren't connected. The car was so ghetto when I got it, I'm not really surprised.


Funny thing is, the car starts even with all those hoses wrong or disconnected, but it only runs if I'm on the gas.

The first picture is for your boost sensor (passenger side shock tower).

The last picture is your temperature gauge sender.
