fuse block diagram?

I have a friend that has a 2007 century. His fuses aren't marked by anything. Does anyone have or know where I can get a diagram so we can find out what's what?

I'm trying to find a fuse diagram for a freightliner century class s/ t CV so I can check for blown fuses and not hurt the truck
