Has anyone found switched and constant power in their 2017 Prius Prime? I ask because I cant seem to find within the fuse box. I am installing a dash cam and would like to set it up with a parking mode which requires switched power.
The Electrical Wiring Diagram (more info) is the best source for this information. You might find some of these previous threads helpful, too: Installing dash cam behind rear view mirror? | PriusChat Best way to hide dashcam cable? | PriusChat The A Pillar | PriusChat Fuse Size for Fuse Tap for Dash Camera | PriusChat Has Anyone Installed a Dash Cam? | Page 3 | PriusChat Some relate to the fourth-generation Prius, which is similar but not identical to the Prius Prime.
If you have prime advanced with the garage door opener auto dimming mirror, constant and switched power is available there. I found an adapter that allows you to tap in. Not sure if that same power jack exists on non-Advanced. You can easily pop off the cover and check.
