I've had a double din kenwood fitted for quite some time now. The other week I fitted a reversing camera. Had everything working 100%.

I know the camera powers up as I can press a certain button on Kenwood to go to rear cam screen, and the image is there.
There is a small power lead that runs the length of the video cable, I think this might be causing the probelm.

So really all I need is a signal(wire) to connect to the reverse monitor cable on my kenwood
And then I don't have to worry bout the one that running down the video feed cable.
Any help , gratefully appreciated.
