I finished about an hour ago, having installed a billion subwoofers, amps and various other components over the years, it was a breeze!
It was only 1 AV cable that ran to the radio, everything else (2 cables) ran to the reverse light, i snaked it all through the factory rubber passages.
It's certainly not OE, but it cost under $60 complete.
I used a $35 camera from a US Ebay seller.
The worst part was dremeling a hole in my brand new car!
Thank you SXVdc for the help and the harness!
