    Hi folks,
    I was a member of Prius Chat when I had my 2007, got out when it died and I temporarily got a RAV4 hybrid, but a year ago Jan, traded that in for a 2024 Prius Prime. So I'm back! :)

    After my dashboard started flashing with all sorts of error messages on Monday, I took it to the dealership today and found that rodents of some sort have chewed through the wiring and caused all sorts of havoc.

    After I get it back, am planning on trying one of those electronic things (a near perfect 5 start rating on Amazon) that goes under the hood, but not sure where to connect it. Another site said connect to the 12v battery, but they realized that for the prius, the 12v is in the back, so that wouldn't work, and then suggested getting a fuse tap to connect that in the front and then connecting the device to that.

    Just looking for the best way to connect the anti mouse device under the hood. I've used other sonic things to keep cats from my deck, which seemed to work, so given the ratings of the one on Amazon, I'm hopeful that it will work as well.

    Suggestions? TIA

    Wow that's a bummer and potentially big bucks.

    There's a fusebox under the hood that has a line that goes direct to the battery.
    Maybe someone with knowledge will chime in.

    I would opine that the device should have its own fuse and that you want to be careful with powering that thing for any amount of time because the battery is small. Calculations should be made and maybe use a protective low voltage shut off device like with hardwired dashcams.

    Did this happen over the winter? I wonder if the charging may have created attractive warmth.

    Good luck.
