reversing camera install

Hi, recently I bought a Navman My escape GPS and a Navman reversing camera, my problem is I have misplaced (lost) the installation booklet for the camera. Coming out of the camera there is a black AV cable that is self explanatory, there is also a red wire and a red with black trace wire. The red wire I presume goes to the reversing light and the red with black trace goes to earth. Could someone please tell me if this correct or if I'm wrong tell me the right way to wire up the camera. Any help will much appreciated....cheers.
