In situ along with the connecting duct. It was a real s*d to drill the holes for the outlet bracket, the combination of a round tube + 90ยบ drill attachment and a shortened drill bit just gave me enough room to get the job done:

I also have some work to 'box in' / cover the various sharp edges under the dash in this area which should hide the ECU & wiring currently visible.
