Hello,
I am trying to tap this portable head unit with integrated dash cam into my fuse box so as to not drain power from the battery when the truck is off. The issue is, when I hooked up the multimeter to the fuse box on the driver's side, I couldn't find a good fuse to tap into safely. I was hoping that I could use either the cigarette lighter fuse, or the auxiliary power fuse, but when testing, both of those got 12 volts when the truck was off. Any recommendations on the best fuse to use?
