Need electrical help for backup camera install.
I'm in the process of connecting my backup camera. I tied into the reverse wire that sees 12 volts when the car is placed in reverse. The problem is, this wire is for some strange reason getting 2 volts as soon as I turn on the ignition. I even checked the voltage on the reverse bulb socket and got the same 2 volt reading with the igntion on and lights off.
I believe I could install a relay and make it work, but that's a PITA and overkill for this.
Suggestions welcome.

Mine is a flush-mount camera. I drilled a hole in my license plate and mounted it behind.

The head unit sees the voltage, causing it to display the camera. The problem is it's doing it when the cars in other gears. Also, 2V is not enough to power the camera, so its displaying a blank screen.

If I had to do this I would use a 2 volt zener to block the voltage, this will drop the operating voltage by 2 volts also eliminating full power which could be an issue.
The simplest approach is to use a relay as your stand off, and then you would be able to get normal operation. The relay could be a small 12 volt single pole relay and you would not need any additional wiring. See my sketch below.
I have made a sketch of the relay, and a wiring diagram. When the relay sees about 8-10 volts it will PULL-IN and power the output pin C. Should do all you need, relay to be as small as you have, no current to speak of here.

That was it! Thank you very much and thanks to the other's that offered great suggestions as well.

Re: Need electrical help for backup camera install.
My wife bought it for me off Amazon, so I'm not exactly sure what it cost. I belive it was around $15, but no more than $20-$25. Below is a link to a similar camera on ebay.

Re: Need electrical help for backup camera install.
Pretty easy to figure that out... Will not ship to Canada because its too fleckin cold up there the pixels would freeze and drop off the screen. And China? Why they make them there... No one would install one of those in things they own because they know how they are made. (He he he he he)
