Got my REAR VIEW CAMERA installed and love it. I ran both the video wire and reverse gear wire together back to the rear of the car. I connected the reverse gear wire to the backup light 12v hot wire (red) along with the power supply wire of the camera. I then made my ground connection to the black (neg wire) of the same backup light wiring to complete my power connections for the camera. Works like a charm... very clear even in low light. In almost complete darkness, still works with a little grain in the picture.... LOVE THIS ONE! I put my car in reverse, picture comes on, out of reverse, picture goes away and Kenwood screen returns. LOVE IT!
