Hey guys, I hope this is the correct sub-forum for this question.  I am going to be wiring up a back-up camera on my car, that will display on a 7.5in in dash LCD.

The screen does the autoswitching between sources, when the camera produces signal, so thats not an issue.  What I want to do, is have the camera turn on with the reverse lights automatically, and also be able to manually turn it on with a switch.

Heres the (admitedly simple) wiring diagram I sketched up.  Does it look correct?  Any suggestions would be much appreciated!
