Fusebox Questions

[BIGSLVRXJ]

So I got to pondering, how does the fusebox work? I've never actually had the nerve to tear into it and when I melted my previous fusebox I had it replaced by a shop. What does the inside look like? Obviously I've seen the face of it and the back of it that is underneath the brake booster but how do the wires come into it and how does it get power? Does the power come straight off the alternator? There isn't a battery cable running to it. Does anyone have pics of the inside where all the wires connect? My inquiring mind is dying to know! Thanks guys.

there is a little magnet inside each fuse of the fusebox. when you turn somthing on the fuse becomes magnetic. thus sending power to the aexon flux.

So how do the wires connect back there? Do you just pressure fit them into the terminals or do they crimp in somehow?
