I have a 2012 Prius 4 and plans to add a dashcam. The manufacturer hardwired kit comes with mini fuse plugs where I can plug directly into the fuse box under the dash without using vampire taps. I was wondering if anyone has mapped out the unused fuses for which might have constant or accessory power. I would prefer to leave the existing fuses alone if possible. If nobody has it, I may do some investigation on my own and post back here.
Some tapped into the rear view mirror years ago. It may not provide power to the camera anymore has modern cameras takes up more power / amperage.
The auto-dimming rear view was a great choice. It has constant and acc power available right where you need it. I had done that in the past as well. I could tap these lines, but since i have the install kit would prefer to go right from the fuse box. The rear view camera has an install kit that has mini-fuse plugs and, for the constant power connection, a small inline piece of electronics that won't bleed the battery down too low. I have had this connected to my Gen2 and now sometimes don't start for a week and never had a problem. The constant power is for a 24 hour surveillance that takes pictures every so often and for a shock sensor.
The tap fuse must cost an arm and leg, I don’t blame ya for wanting to put it into use then. Bye rear view view mirror power source.
I think the price on Amazon is $22, but the manufacturer has sent me this on multiple occasions for free to go with the dashcam.
