Installing new stereo: wiring confusion

Hello friends,
I have a Nissan Sentra 2007. I recently bought a new stereo and figured I'd hook it up (YouTube showed me hey just hook the same colored wires together), well turns out it's not that simple..
The wires a colored differently and are unequal in number.
To make it even more fun, the manual for my new radio doesn't say much about the colors (page 16 http://www.pioneerelectronics.com/St...nual112712.pdf).
In addition, the back of the stereo's are completely different and confusing - what do I plug in and where!?

Attached are pictures of the harness etc.
The car connector has a list of the colors and functions (in image), but the stereo one does not. So, I will post a list of the colors below, as well as attach an image.

Colors:
Purple
Purple w. black stripes
White w. black stripes
Grey w. black stripes
Green
Green w. black stripes
Red
Yellow
Grey
White
Black (longer than the rest)
Blue (says system remote control on the tag)

Please help,
Thanks!

EDIT: Also, I am unsure of where a good connection spot for the chassis ground wire would be. The one with the metal ring on its end (car connector harness)
