I have car reversing camera with a permanent power supply with a switch to turn it on & off. I want to also have a supply from the reversing lights to turn it on when parking and the permanent supply is turned off. I presume a relay will work but am unsure how to wire it up. Reason is that the permanent is for when caravan is attached and second camera is working all the time when travelling. I realise I could just flick the switch but it can be busy when parking and would be good if this can be done. Hopefully someone can advise me.
Main problem is what happens if I hook both up together and rev supply comes in when perm is still on
Thanks

Can I just connect the second wire from the reverse lights to the positve between the switch and the monitor and put a diode in each line to stop backfeeding to each other. Some advice would be good thanks
