My reversing camera has turned up today. I am intending on using it with my garmin sat nav and have the appropriate lead to connect the av cable to it. My question is this - what is the easiest way of picking up the 12v power for the actual camera. I know it can be done by using the +ve to the reversing light - but how exactly do I do this? My van is a 2010 Fiat Ducato. I've had a look at the rear lights and presume that somehow or other I need to connect to the correct wire in the electrical block that is connected there - is this how others have done it? There is already a bolt to the chassis near the lights that has a couple of wires attached to it - I'm thinking that these are the grounding ones and I can just connect the camera -ve to this. The alternative is that the av cable also has a trigger wire running through it. Would this be able to be connected to the camera +ve and then to another +ve at the monitor end to provide power as and when required? If so is there such a thing as a male cig lighter that has an input for just a +ve wire - most seem to have inputs for +ve and -ve? I'm trying to not over complicate but seem to be going round in circles at the moment on this one!
