fuse block

Hi I have a 2005 Cobalt with upgradrd audio.... my radio quit and when i went to change the fuse the fuse block diagram on the inside fuses does not look like the real thing. Do they put some kind of cover over the fuses to tap for upgrade amp and speakers ??? Kinda has pink wires coming from...

I'm trying to install the Alpine "Imprint" Processor (I've already installed the Alpine receiver and speakers). The positive wire for the processor already has a fuse built in, is there a way I can add the wire to the fuseblock? There appear to be open spaces on the fuseblock and I'd prefer not...
