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.
Responded to your PM before I saw this. Bavarian can be funny about doing Ad Hoc stuff like this. I’m sure you can find a shop to run two wires from the BDC, especially if you tell them exactly what to do. Here is a schematic, this may help tell you which pin the fog wire should be in if you had it.
