I'm hard wiring a dashcam in my 2007 Sierra. All of the fuses in the interior fuse box (left side) test out as powered with the ignition off. I'm looking for a switched power source inside the cabin, and would prefer not to splice wire if possible...I'm hoping to use an 'add-a-fuse' adapter.
I found a couple of switched fuses in the panel under the hood...if I have to run my wire out there, what's the best way to do that?

I appreciate any help you can provide,
