2009 Broadway EK TB reversing camera

Morning everyone,
Our new to us 2009 Broadway has a reversing camera fitted with the Veba over the mirror monitor. Unfortunately it doesn’t work and I wondered if anyone had a wiring diagram so I can test whether it’s the camera, monitor or both that’s at fault. I’m assuming there is a fuse somewhere but I have yet to find it.
Any help, info or advice would be greatly appreciated 
Thanks
Doug

On our 2013 Broadway the connections from the camera and the monitor including power supply is in the cab behind the headlining accessed by removing the light. The outer light cover just clips on allowing the lights to be removed (not disconnected). Then you can access the wires for the camera, there is a fuse there if I remember correctly.

Thanks for that, turns out it just needed the connections cleaning up and it’s now working
