I installed a set of 6k hid's on my 2014 B7. It was a bit time consuming. I had to remove the grill and the headlights for easier access. I did not have to tap into the wires. I purchased the adapters for a extra 25 bucks and they went right in. They were a little tight but they worked well. I only got 1 side to turn on, the other side seemed like the bulb might have been dead? It was cloudy in the bulb itself, not sure if that was the problem, but I emailed deautokey and am waiting for a response. I also did scratch up my headlight a little bit too, maybe there's something out there that can remove the scratches? The headlights were a pain in the ass to put back in, but that being said there is finally a kit with adapters for the B7 without having to splice into any wiring.
