Backup camera with manual on switch question

[2005yukonxl]

Ya'll read my thread im sure where I put the backup camera and monitor in our yukon....easy.

But now im gonna do one in my dad's 2006 silverado as well. but on that one, im working out a way to wire it up so he can have it for a backup camera or a manual override to turn it on to watch his camper when he wants to.

so, i come to the TYF peeps seeking wiring wisdom. Whats gonna be the best way to do this. I think if i can find some sort of 3 way switch...and have it to where i can connect the backup camera and monitor to the reverse wire, then middle position would be off, disconnecting power from the monitor and cmaera and the third position connecting camera/monitor to 12volt ignition power. what sort of switch would be best? any ideas or experience? am i looking too simply at this and gonna need some diodes or something? i was thinking if i had a switch that would break the circuit before making connection to the other power source, i can keep it simple.

all you have to do is mimic your reverse trigger with a switch. if your trigger to turn the camera on while backing up is +12v, wire a switch to +12v and connect it to the wire. you can run a relay to prevent feedback or use a diode. but its nothing complicated

It is very simple, I did it in my Hummer H3, just need to have a relay between the switch and the reverse wire so the reverse bulb doesn't luminate when the switch gets engauged
