Car Back-Up Camera - Finding Positive and Negative Back-up LIGHT wire polarities -Video #1

Car Back-Up Camera - Finding Positive and Negative Back-up LIGHT wire polarities. That is how to find out where Back-Up Light socket is located and then determine which of the two metal contacts inside the socket is the positive (+) side and which is the negative (-) side. Then I show you how to tap into those wires going to the socket to hook up your back up camera leads. Note I purchased this Car/Truck back up camera at NAPA Auto and it only came with a dashboard Video monitor and the camera. Thus the transponder must be built inside the camera and sends a wireless video signal to the monitor on the dashboard. Make sure you are not on a hill or a sloped surface when you put the car in reverse with the car not running and no one being in the drivers seat. Thanks, please subscribe and like.
