This is our 10M (1000cm) version of the RCA Phono extension cable with built in "trigger wire". You will notice that there is a small red wire coming out of the end of both ends of this cable. This is an additional wire that we have had installed, designed so that you can send a reverse light trigger supply to your monitor - telling it when you are in reverse gear. We have also seen people use this spare wire to send power from an ignition source at the front of the vehicle to the red power wire for the reversing camera.
