Wiring diagram for TTMk3 (Audio install)

[Gnasher]

Hi all,

Does anyone know of (or even better, have) a wiring diagram for the audio system on the base (non B&O) stereo in the Mk3 TT at all. It's a 2018 RS if that makes a difference. Looking to add a small install to make up for the non B&Oness of the car.

Ta in advance.

...or even an idea where the speaker feeds originate from (behind glovebox or in boot?)

After all that - found one online.
