Hi , had a chinese ICE for couple of years now in my octavia 1.9tdi 2008 , just fitted reverse camera but it only works when ignition is on , when you start the engine the video from camera wont display, apparently I have to fit a 12 volt relay to connect the camera properly , at the moment i have the camera power from the reverse light and also reverse trigger connected to reverse light as well, how would i fit and wire relay up ? any help would be really welcome because i've no hair left !

sorted, I ran positive from cigarette lighter in centre console under the carpet and rear seat then into boot and fitted relay under the boot lock trim ,connected reverse camera and now everything works brillliant
