I don't think OP is going to be providing his full writeup.......
Anyone else have any luck with this, that would have some guidance/advice? Planning to do this to my 2018 Alltrack S soon, looking to swap in Audi S3 seats (front and rear). Concerned about the rear seats, and loosing the ability to drop them quickly from the trunk area using the lever, as I use that feature somewhat regularly.
Saw a post on another forum of someone swapping in S3 seats into their mk7, and they bought a custom wiring harness, but I couldn't find the info on the harness, and that forum is a pain to use lol.
