Switched 12v power source?

I have an 07 Silverado Classic 2500HD LBZ EC SB. I need to wire in some accessories that need power only with the truck running. Where is it recommended to tap into a switched 12v source. Is there a switched power tap in the dash fuse box or the under hood fuse box? I could find nothing in the owners manual that recommended a source.

Im just doing a little studying before my radio install, where is the best location inside the cab for switched 12v source? Keep in mind I havent even opened the truck door yet!!
Just looking for a place to hook up power for my new head unit. I have all the correct harnesses for it but as far I as I can see now the only thing not in the harness on the truck side is the switched power lead. Gonna look at it soon this morning. Still listening if there are any more comments..thanks
