'22 Expedition: accessories-controlled fuse?

[nationalgallery]

I'm trying to install a dashcam that needs a +12V line that is active with 'accessories' — so it would power off when the accessories power times out. It looks like the power to all the fuses in the interior fusebox is always +12V—none seem to go to 0V. Am I missing something, or any suggestions where to access an accessories-controlled +12V source without having to tear the car apart....?

I finally found 3 fuses in the interior fusebox that are only active (+12V) when engine is running or 'Accessories' is on:
35 - 'not used'
36 - image processing/park assist
37 - heated steering wheel

Thanks for sharing!

@nationalgallery Were you able to use Fuse 35 successfully?

I used 37- heated steering wheel and it works fine. Just put a fuse tap in, no additional wiring needed.

@Tuck Did the fuse tap sit in properly? I am afraid they might not be snug enough.
