I finally tested to install a battery switch for the negative/ground terminal on the annoying trunk battery placement in my gen 2s. I wish to recommend this to everyone DIY since it makes me able to cut power over winter or when doing maintenance work without even removing one piece of the trunk pieces. Just by opening the right backlight cover I am now able to reach this switch and cut 12V. This might have been posted before, but I failed to find anything like this. I bought one version from temu first, this had the best design in my mind. I had to grind the pole down a bit, but this version has adaptable screws that easily fits the small sized poles that the Prius uses and locks them into place real good.

That's a great looking design but there's no way I'll buy it from Temu. I wonder who else sells them?
