FM DAB retain T6.1

[dave033]

Hello,
Just a quicky But does anyone know if and where these need to be connected to?

Talking about the blue wire with the clip on the end. These are on both Dab and fm retainer adaptors.

HU: Alpine Halo 9
Vehicle: T6.1

Thanks

So I've been hunting the internet and think it might be one of these 3. Is that correct?

All done,

Installing was like defusing a bomb backwards.

If anyone finds this in the future I used the remote out but I think any of the blues are fine.
