RNS-E 192 wiring question

[Zyox]

Hi all.

Posted this in the B7 RS4 forum but I know a lot of you run these units in other cars so just hoping someone can help me with this.

Have an OEM 192 K RNS-E that came with my 2007 B7 RS4.
Trying to wire up a CarPiHat to the car which needs:
- constant 12v
- switched 12v
- 2x ground
This will be for a project that essentially runs a mini computer and I only want it running when the RNS-E is running so I figure it makes sense to wire it off that.

Can anyone advise which wires to splice into please?
I have an extender cable for the loom so should make it less risky.
So far I'm guessing to use:
- Switched 12V: B10 = U14 ST CDC
- Constant 12V: no idea
- 2x ground: both into D14=DWA-GND

Any thoughts or help appreciated. Thanks!
