New to me Blazer

I finally am upgrading from my 2001 Blazer to my new to me 2020 with the punchy V6. I love it! I am already trying to find things to add to it. Currently in the conundrum of finding two 15 amp fuses in the dash fuse box and then determining which one is switched (ACC) and which is constant (battery). Plan to black it out eventually! Hopefully I can get this rear view camera mirror installed first and I'll post an update. Glad to be in the community!
