Anyone figured out how to get around this? Found plenty of videos of other models/years of moving a fuse from one position to another to change this setting to turn off aux power when you turn off the van, but the 2022 express fuse boxes don't seem to have this option for any of the fuses related to aux power. BTW, just read that sentence back to myself, not my finest English. But it's late so hopefully I got my question across.

 

Please explain why you want to do this, and then maybe we can offer an easier solution, because changing the existing wiring probably isn't worth it.

 

The aux power is always on, even after turning the van off. So it's a drain on the battery and a waste of memory card storage on the dash cam.

 

OK so it sounds like you want your dash cam to turn off when you shut off the van.
You'll have to put a relay in line with its power source, and energize that relay from a circuit that's only hot with key on, such as A/C or power windows.
