Hello everyone,
Newb here (was a 12v installer way back in college and would use this site for diagrams and what not). I went to install a dashcam on my 2017 Prius Prime (not the standard Prius) and am having all sorts of trouble finding switched power and ignition. Does anyone here have any experience in finding such? I pinned out the fuse box, found circuits that looked good, but after the car sits for a certain period of time it seems like the circuits change?

Thank you for this! May I ask where you are able to find this information? I assume "ignition" and "accessory" are the same as switched power?
I'd love to be able to find the actual OEM schematics- any tips where I can find that level of detail?
