I have a 2011 Nissan Versa S hatchback. I thought that I would be able to remove the taillight assembly and connect the power wires for the camera at the reverse light. Unfortunately, all the wires at the taillight assembly are black, so I don't know which of the three that lead into the backup light would be positive, and which would be ground. Apparently newer models actually do have different colored wires at the taillight assembly, but mine are all black. I saw a video that showed a sedan, but I haven't been able to find anything on how to resolve this problem in the hatchback.
