Bringing up an old topic...

I'm exporting my 2020 540i to Europe and prepare - as much as possible - the vehicle to pass the road test smoothly upon arrival. Today, I installed a set of pre-LCI Euro tail lights that have the rear fog diodes (LEDs). I also installed a Euro light switch (for a rear fogs only, no front fogs, no lane assistance).

Not completely unexpected, I discovered that I do not have the wiring. At least not what's in your picture. You mentioned that a wiring in slot 1 and 6 must be present for the fogs to receive a signal. Suggesting that typically those slots are not in use. However, I noticed that I have slot 1 and 6 in use (and 2 and 5 are empty). See pictures, left and right, respectively.

Any idea what is going on? Or is this a matter of coding?

I requested Bavarian Performance Group (Winchester, MA) to do the wiring for me but they have no appetite for the work. I'm now looking at Sound In Motion (Watertown, MA).

Thanks for your advice.
