Hi,

I was looking at hardwiring a dashcam, but I want to make sure I pick the right fuses. I have to first check which ones have constant power (parking mode) but first wanted to check if I can even use any of these near the passenger side or am I forced to use the ones in engine bay (safety wise). https://www.mazdausa.com/static/manuals/2023/mazda3/contents/07031600.html?kw=FUSE%20BOX&hw=FUSE%E3%80%80BOX

Thanks for any advice.

Here are the power distribution wiring diagrams so you can see which fuses have constant power and which ones are switched. This guide can help as well:
