Trying to connect a dashcam battery to the passenger side fuse box inside my 2021 Yukon AT4
The battery requires a switched fuse that will turn off when the vehicle turns off so it doesn't drain the car battery.
Does anyone know which fuse switches off when you turn off the vehicle? The ones I've tested always seem to be on or off.

just use fuse 26 usb/rap, it will have power for a few minutes (up to 10 minutes) after the vehicle is shut off which is fine for your dashcam, you can test it with a meter just roll down the window and attach your meter, then lock the vehicle and wait up to 10 minutes and you will see the power go off.

It runs the USB ports and relays for the other circuits that keep power when the ignition is off. RAP stands for Retained Accessory Power...... By the way, that is the only fuse/circuit in the ENTIRE vehicle that is switched with ignition, all others are constant hot. Took me forever to find it, had to read through the 900 page electrical breakout guide from GM Upfitters to find it.

This is helpful. I needed same info. Is there a fuse in the passenger fuse box which would be safe to jump for battery power (always on), for parking mode? Thanks.
