If I unhook that and just power the camera from a 9v battery, the signal to the mirror is nice and clear.
Hmmmm interesting, I remember reading somewhere about the power going to the stock camera being 6 volts. Maybe the green write is only provoking 6 volts and that is why the quality is crappy. I'll plug mine into a different power source when I get home.
