Thanks for the info! I was able to successfully install the camera in my 2013 SV. I discovered during the installation that is not really necessary to replace the two wiring harnesses. Simply run 4 wires from the camera to the M21 connector in the left kick panel by the drivers seat. Like this:
Camera --------- M21 Connector
Red --------------> White Pin #24 (+6.2V)
Black ------------> Black Pin #25 (Common)
Yellow ----------> Red Pin #9 (Video)
White -----------> Black/Grey Pin #8 (Shield)
Then connect M21 Black Pin #7 (Camera Sense) to chassis ground.
That's all there is to it! Works like a charm.
Grounding Pin #7 lets the AV unit know that a camera is present. The AV unit detects when the car is in reverse and applies 6.2 volts to Pin #24 and this turns on the camera.
I did this on the SV. I expect it will work on the S as well.
