I'm currently looking at my reverse camera on my recently purchased 2010 Sedona 3 which isn't working. I removed the camera and dismantled it fining lots of contamination inside so I assume it is dead(I cleaned it with electrical spray and tried it but no joy). I was wondering if anyone knows what colour the video wires are and is it possible to connect an aftermarket camera. There are only 4 wires - red, black yellow and white. I assume 2 are power and earth and 2 are the video but not sure which. Any help would be appreciated.
