OK! Installed this DVR today, doubling as the backup camera for my '13 SL.
I had to mount it high because when it was located in the lower window it couldn't look straight down without the window sill being in most of the frame.
I still have to lower the aim a little, but need a elbow plug for the video output on the DVR, since it's on the top of the camera and runs into the glass right now when I try to aim it down.
The wiring discussion I used to install it is located at http://www.mynissanleaf.com/viewtopic.php?f=37&t=10107&start=110
Found my super black 2013 Leaf.
