Where do the auxiliary coolant pump hoses attach?

Hi Guys
I am stretching the limits of my mechanical abilities by swapping out my 2003 1.8T AWP with a 2004 AWP.
I never pulled an engine before.
Amazingly, I have all of the mechanical bits put back together.
All the hoses almost back together, but I am stuck.
I think that the small pipe coming out of the auxiliary water pump (outlet?) attaches to a steel pipe that goes to the turbo.
Where does the other hose attach?
I seem to be short a place to attach it?
If you could give me a clue, I would be forever grateful.
Thanks
Dwight

Re the pump itself, I'm sure the pump pulls hot coolant from the turbo and sends it to the rad.
So it is the Intake on the pump that connects to the pipe from the turbo, not the outlet.

The ports on the pump should be labelled, maybe just arrows.

I think the coolant goes the otherway, as that little pump wouldn't be able to pull coolant through the block that, is surely the drain. Its job is to stop the coolant boiling in the hot side, so it just keeps it circulating..

Unfortunately the coolant flow diagrams in the Bentley manual doesn't have arrows on the electric coolant pump pipes in the 225 diagram.
But the flow through the pump is in the end and out the side.
ETKA shows the pipe connected to the side outlet going to the "T" piece in the rad top hose.

Thanks Stuart!
There was no tee on the new hose I bought, so I spliced the old one in where it shows on the drawing and where it was on the old hose.
Thanks all!
Hoses are all reinstalled. Power steering piping reinstalled.
The bushing that I lost to be able to remount the AC compressor arrives today.
Started on the wiring last night.
Cut the ECU out with a reciprocating saw.
It wasn't pretty!
Today, I am hoping I can cut the wire looms open without doing any major damage!
The wiring (most of it anyway) came with the used engine I bought.
I plan to use as much of that as I can to preserve the connections on the engine.

Thanks again for the help.
Dwight
