noob harness question yet again.

I know there are lots of posts about this but it seems like everyone knows something I don’t...

I have drawn a little picture of my 2003 A4 the top one is the Audi one and the bottom is my iso. When I connect my Sony MEX-R1 to the connectors it will accept CD's and eject them but wont turn on. Making me think the HU thinks the ignition is always off.

Are there some wires to swap or link together?

I was told the sound system was Bose so I bought a Bose harness adapter
although I now no my cars doesn’t have Bose. It should still work with the Bose adapter right?

thanks for that. i got it working but distorted at lower volume and less bass, so ill keep my audi one in for now.
