Attempting to install 2012 radio into 2010

Hello new member and first post here. As the title suggests I'm trying to install a 2012 radio onto a 2010 Prius. I've currently purchased these parts off a 2012 Prius: a radio, steering wheel with phone controls, over head microphone within the lamp assembly and the back-up camera. I've tried to plug in the radio before, but there were missing plugs and some plugs didn't fit. So if anyone provide me a link to the required wires for this to work that be great. I saw an old post here before, but the pictures were inaccessible, so I couldn't tell what I needed even when I typed in the name of the parts on eBay a bunch of different wiring came up.
