What am I doing wrong with this dash cam hardwire install?

Trying to install a hardwire for a dash cam and can't get power to it. I have tried two different dash cams, two different hardwire kits, and two different add a tap fuses. On my current attempt, I am using an "E Support 12v Car Add-a-circuit Fuse TAP Adapter Mini ATM APM Blade Fuse Holder." I crimped the power line from the hardwire into it. It came with some fuses so I put one on the back of the holder, and then took a 10amp fuse out of the "TOWING BKUP" slot from my 2016 4runner. I then put that fuse in the empty slot on my tap a fuse and plugged it in. I grounded it by running the ground wire through a metal hole near the fuse box and then covered it with electrical tape. On my other install I ran the ground wire through one of the rear bolts. No power on either of them. Am I using the wrong fuse slot or doing something else incorrectly? Thanks for any help.
