Hi, I dont find info about reverse light wire. Does anybody have done install to manual trans. car reverse camera and found correct wire (reverse light) for take signal? My camera needs signal from reverse light wire to work. All other things have done to get it work, only that missing.

I found reverse light wire! In trunk on right side, take off the side panel (no need tools for that), right down bottom corner comes in trunk four wires (as I remember right). There is black/green, purple, black/white and some other. Correct wire is black with white stripe. There U can get good signal for rear camera :)
