Blaupunkt Frankfurt Installation Wiring Help

[Jam911]

I got my E30 a Christmas Present a Blaupunkt Frankfurt
My car has an analogue electric aerial so I also got a DAB aerial adapter.
My question is the DAB aerial adapter has a live and a red (+) and a black (-) wire and as I understand it I have to connect the red wire to input A5 on the diagram and the black wire to A8 on the diagram.
Am I correct?
I wanted to get a second opinion before I go ahead.
Thanks for any advice.

Yes correct, A8 is the ground and A5 is the aerial power output from the radio when it is switched on.
