Switched Fuse in Under Hood Fuse Block
Hi. Can someone tell me which fuse(s) in the under-the-hood fuse block are ignition switched?
Actually, I prefer to use the either the fuse block in the passenger side of the dash or under the passenger seat, but I don't believe any of those are switched? If there is a switched fuse in either, which one(s)?
I do know how to check, but I was wondering if someone knew off-hand as the suv isn't readily available. Thanks!

Fuses 23 and 25 in the trunk are for Radio systems (COMAND, etc.). Check those.

If you're looking to power something small, the power outlet under the glove box is switched and not hard to get at the wires. That's where I tapped in for my dash cam to hide the wiring. I just used an inline 5 amp fuse becasue the camera wires are smaller and that port I believe was a 10 amp fuse.

Now, instead of hard wiring, I can plug the battery pack into that socket and my BlackVue into the battery pack.
If anyone sees any problem with this, please let me know. Taking up space in the power port is not an issue as I have a dual port adapter and the only other things that get plugged in there are cell phones.
*If i knewed that before, I wouldn't have hard wired my radar detector, either.
Thanks!
