Right I am stuck. I wired it up to the rear light and selected reverse gear while I had the radio on and nothing happened. I went into my video 2 setting and I had no rear camera showing up, I then selected reverse gear and on popped the video camera. So the only way I can have my rear camera on is by linking both sides up to lives and pressing the video 2 button everytime I want to reverse. It means I can watch the traffic while I am driving behind lol :crazy: . I would have liked it to be on when reverse gear was selected but my Pioneer has a different camera port for Pioneers own reverse camera, must mean I am stuck with it the way it is. What I also did Matt was join the live up from the camera and join it to the red wire coming from the yellow RCA lead in the boot area as they both needed a live feed anyway, so I let them share. Is that what you did?
