Passat (B7) :: 2013 - Converting To LED Taillights

I have a 2013 Passat SE. I have a few questions for those of you who have converted to LED taillights;

1. What year Passat do you have, and what trim level (S, SE, SEL)?

2. Do your LED taillights flicker when you first turn on the ignition? This would be a computer generated test sequence.

3. How long did it take you to do your conversion?

4. Do the outside black plastic trim pieces, on the trunk mounted lights, fit well? If not, what did you do to correct this?

Since I am not mechanically inclined (other than basic service), certainly not wiring, I asked my local dealer if they would install them for me. Their foreman is working on the car because I wouldn't be charged for every hour spent on the car. It is still likely to be a big bill, and I am beginning to wonder if it was worth it. He has spent an hour or two each day since Monday or Tuesday, plus several hours today. The lights work very well. Even the rear fog light. So, I am happy with them. However, the foreman is still tracking down a persistent buzzing sound which will likely be solved with one or two ground wires. The lights don't fit as well as the stock do, but the imperfections are hardly noticeable. On the trunk mounted lights, the black outside trim pieces barely stay on. My guess is if I shut the trunk with any force they'll fall off.

The foreman has had to completely re-wire my taillights, all the way through the door sills to the BCM. I had provided the instructions that I downloaded from this forum in another thread, however he said those instructions were for a 2012 SEL Highline Passat, which is different from mine. Note, I bought the Chinese LED taillights.
