Ford Explorer Radio connection HELP

I would like to replace the radio in my daughters 96 Explorer XLT. Can anyone tell me how I can find out which wires go to what on the connecter that I will unplug from the factory radio? Like which is power? Which is to speakers? Is there a schematic anywhere? Is there and adapter plug maybe? Any help will be greatly appreciated. Thanks in advance. Ken
