You will not find a harness yet for this retrofit as there is no retrofit for it. This is a custom job.
- You need to create your own harnesses, at least three of them - Quadralock (media 2 main connector) to main connector (high 3), ethernet harness (high 3) which your car does not have, and RAM harness/speakers.
- High 3 requires a RAM module in the trunk as there are no tuners in the High 3 -tuners are in the RAM.
- Speakers are powered by the RAM + High 3. The Media 2 HU power the speakers directly (via Quadralock). There is no RAM in your car.
So the video of the iDrive 6 to 7 is missing all the custom work behind this retrofit, that is perhaps the reason they will not answer your questions.
My suggestion is to investigate the possibility of flashing a Media 2 HU with iDrive 7 (or maybe you will only need a more recent version of a Media 2 HU with native iDrive 7), and look for what is needed to retrofit the digital display. That would be much simpler and cheaper than going full High 3.
