Default Switched Power

I'm trying to find switched power in either fuse box. Has anyone successfully located a fused that has switched power? Doesn't seem like it should be that hard, but I have come up empty so far.
Thanks for any input.

The rear fuse panel behind the waterfall. F14 I believe. Been a long time. Test that with a light for keyed. I have an add a fuse there.

You didn't say what it's for and if proximity is an issue. I pulled switched power for my dash camera from the passenger side vanity mirror. Powers up when door opened, stays on for 10 minutes after car is shut off. Works like a champ.

That said, you can sign up for AC Delco TDS subscription of the service manuals, $22 for 3 days. They have the wiring diagrams.

The #50 fuse in the fuse box behind the glove compartment is switched power on my 2020. It is the fuse for the accessory outlet by the glove compartment and uses a 15 amp MCASE fuse.

Is it switched instantly or does it power down a short time after the ignition is off?

It goes off once the driver's door is opened after the engine has been shut off (as I remember). A nuance is that for some reason the power is momentarily interrupted when you open the driver's door even with the engine running.

A lot of the circuits stay live for 10 minutes, then shut off. If that's acceptable for your use, leave the passenger door open for 10 minutes and then check the circuits. Oh, and leave the keyfob in the house. Some circuits wake up when the fob is in close proximity to the car.
