I've been following this thread since last September when I started planning the installation of the Park Assist module/sensors into my MK7 2017 NAR Golf R. I already have the eight (8) Park Pilot sensors installed from the factory and went ahead and ordered the kit from Carsystem last year for the four (4) Park Assist and now have everything prepped for installation. I have all of the installation tools and have the pinouts as directed from Carsystems, which I've validated several times. The only remaining installing step I haven't quite sorted is where to best tap +12V power. I was thinking of tapping the incoming power to the existing Park Pilot module but I haven't taken that plug apart yet to figure out how it would all fit together. I also have done all of my retrofits without permanently altering the original wiring harnesses and have used OEM pins/connectors. I was hoping to continue that. I really appreciate all of the work you guys have gone through documenting your installation process. It's been a big help understanding the process.
