I have a 2016 motorhome with a Fiat Ducato cab and 2.3L 150 engine. I have installed a reversing camera and brought the supply cables out next the the fuse box on the drivers side (RHD). I noticed that immediately to the right of the fuse box and just below it is a cover with lots and lots of wires. I need a + supply only on when the ignition is on and a + for the reverse sensor and of course a - supply. Can any one please advise where near the fuse box I can get these supplies and the colors of the cables I need. I intend to fuse at the point of connection to be safe. Any help greatly appreciated.
 
The problem at the cab end is there normally is no reverse wire as it's part of the CanBus. You have to try and find where it comes out of one of the onboard computers. You could try picking it up from a reverse light or use one of the many can bus units that read whats happening on the CanBus and react accordingly. Canm8 do some different ones.
