2004 Audi A3 8P 3-door – rear window antenna issue after glass replacement

Hi, I replaced the rear glass on my early 2004 A3 8P 3-door with a Benson rear window.(only one in stock and I needed the car…..)

The car has the original 8P0 035 225 B / AU350 antenna amplifier.

The new glass has several antenna connectors, including a 3-pin connector, but my original amplifier has a 2-pin flat input.

I temporarily connected the two antenna wires directly to those two pins and also swapped them, but FM reception is still basically dead.(hacked with that red and white wire)

Before the glass replacement, the radio worked fine.
I’ll attach photos and a video showing all 3 glass connectors and the amplifier.

Does anyone know if this Benson glass is for a later 8P antenna setup, or which connectors should actually be used on an early 2004 3-door?

Those loose connectors doesnt seem to fit anywhere.. I dont have GPS or other sorts of stuff(inspected the trunk connectors also by removing all of the plastics)

In the wide (entire glass) photo you can see all of the connectors that have nowhere to go in my electronics….

Shop doesnt know anything … f these 4.7 google ratings shops man.. I trust no one…
