I recommend installing a fuse inline, close to the fuse box. It's a little crazy to have such a long thin power wire go completely un-fused, if it were to get pinched somewhere or melted by something hot that wire will catch fire, and if you're unlucky other things will too.
Also, I had my bluetooth disconnect while I was driving, and couldn't reconnect even after restarting the car a few times. In case anyone else has this issue, I unplugged and re-plugged the wiring harness and was good to go.
