Adding an electric wiper (and also a USB charger port which is kind of related) to my 12 volt system, and just wondering if there's an optimal place to splice these into the system?

I don't have any kind of fuse panel... Wiper has an online fuse. And while I assume I could probably splice it in anywhere that's hot when the key is on just wondering whether there is a best practice.

Probably overthinking.
