Fuse box - Electrical connections that are off when car is off

Cable is ran. New updated radar detector is installed. I was going to terminate the power cable to the fuse box behind the driver side cubby door. Ground has been connected, but I need to know what fuse block powers down when the care is not running. Put everything back together (A pillar molding, cubby hole door, tucked the cable out of sight in the overhead. BUT! I loaned my power meter to the neighbor to test his dogs invisible fence but he's out of town for a few days or I would have already found which one is dead. I have all the hardware to plug and play the fuse end of the cable, just need to know which one I can use. FWIW, I'm replacing a Escort 9500ix (which I've had 2 for 10+ years but is dated and all the cars with BSM kind of freaks it out. These babies have more then paid for themselves many many times over, but for the price, I couldn't pass up the R3 from Uniden. Just don't want the cord hanging down the middle of the infotainment system so I'm going to hardwire it in. Dash cam is next. And thanks in advance. :cool:

I could have the fuse # wrong, I'll double check it and get back to you.
SC48. Shuts off when the car is shut off. On when you start up. Listed as Not Used and has no fuse of course. But dues what I'm looking to achieve.

There's this


It won't tell you which ones are off when ignition is off but it does show you where the unused slots are. You'll still need a meter/tester to find out which slots are switched with the ignition. I used SC41 when I wired up my dashcam.
Thanks. I ran out to harbor freight and got a cheep ohm meter. I was spot checking and seems everything is "hot" so far. I'll double check C41 but though the detector has the ability to "shut off" if not in use for a certain amount of time to save the battery, I rather have it just shut off when I shut off the car. These things have a crap load of electronics but I agree with the other poster, would have been nice if VW included a list what fuse is what. Don't expect a list of what's hot and what's not when the car is in sleep mode but SC41 stays hot. I ran out and plugged into the slot. Shut the car doors, locked it. Everything went off but the detector. Though the detector has a mode to shut off if the battery drains, I thought it had a mode that shuts off after a certain time. It didn't. So, kind of back to square one. Funny thing, I can turn off the detector. Get out of the car, shut the doors, etc. Detector stays off. But as soon as I start the car, detector comes to life. I don't drive the Atlas that much (it's almost 2 years old and just over 10k miles), but I can get use to turning it off manual.
