I am on a crusade to make my fog lights great again. In my WK2, I could just re-configure the BCM with AlfaOBD. I tried (one of the first brave soul to do it on this board - my exploits are documented on the forum here and over at 4xe) with my WL, and I had some modules refuse to proxy align. By some inspirational-magical-divine-grace I was able to restore the settings and dashboard lights fixed themselves.
2022(23-spec) WL 4XE Trailhawk. With most of the options for that year.
As you know, when you turn on the high beams (automatic), the fog lights drop out. On the WK2, I modified a flag in AlfaOBD. On the WL, it will have to be done with a hardware. I want to thank @AmauryJVL for inspiration: https://www.jeepgarage.org/threads/roof-mounted-led-bar-install.252838/ but I will be doing it differently. I did search and I came up mostly empty - people are trying to tap the interior fuses for cameras, radar, radio.
Automatic Transfer Switch DC 5V-60V (ATS) - one each per fog light.

Proper wiring (say 16 AWG). Proper factory connections. I will get the proper factory connectors so everything is plug-n-play.
WHICH FUSE(s) TO TAP ? Obviously it needs to be a switched power.
I could keep it simple - the headlight fuses. There's a 10 Amp Left and a 10 Amp Right. I could do front grille shutters. Afterall I would like my engine cooled (open grille shutters) at all times. But I would prefer either something even less consequential than grille shutters - preferably for something that I know I do not have on my vehicle. For instance my BSM Valves and another BSM spot are actually empty.
COMMUNITY QUESTION # 1 - Which fuse have you taped before for such projects ?
COMMUNITY QUESTION # 2 - Which blank spots are actually powered ?

The attachment is my actual fuse box in the "anatomically correct" positioning for easy identification. To the left of the fuse box (as photographed) is the windshield, to the right, the front of the car. The 5 large metal bus connectors point towards the engine block.
