Default Identifying RNS-D switched power output(s)

I'm wanting to find a circuit in the RNS-D wiring that goes "live" with +12V when the RNS is "on".
i.e. NOT necessarily when the ignition is on, but also when you just sit in the car and turn the RNS on manually.

I've identified one candidate in the CD wiring, and have used it in the past, so I know it works. It's labelled with a switch symbol and a +.
On the attached diagram it's between the CD-R and DATA-OUT pins of the CD connector.
For various reasons I'd like to avoid using that if I can.

There's a similarly labelled location in the LINE OUT block of that same connector, next to COM.
Does anyone know if it's the same or do I need to pull out the RNS and get my multimeter out?

I presume the LINE OUT block is used for audio to Bose amps and, in non-Bose like mine, for the rear speakers which I believe use an amplifier incorporated into one of the parcel shelf speakers.
Therefore logic suggests that pin is the signal for those amplifiers to turn on, so I should be able to use it.



If anyone is wondering why, it's all to do with streaming to the RNS via bluetooth using the TV input.
That's the round DIN-style connector and the audio is the three "NF" pins - 1, 2 and 3.
But you also need +12v on the VID-ON pin to activate TV input, so I'm looking for an "easy fix".
