Where are sidebar settings saved?

I have tried to figure out where the settings you make in the Finder Preferences for the Sidebar is saved. I want to make a script or a profile that will make every device visible in the sidebar. Standard is only external disks and CDs, but I want computer and hard disks to show too.

I have looked inside com.apple.finder.plist and com.apple.sidebarlists.plist and even compared these files before and after the modification i made in the GUI, but nothing changes (except which tab I was in, in the preferences window).

Does anyone know where these settings are saved so I can use 'defaults', 'PlistBuddy' or a profile to deploy this to our clients?
