If you get any signal from the camera the power return must be coming from the video cable and this could make for a very unstable picture.

Did the decoder come with the camera or did you buy it separately?

Try connecting the black wire from the camera to a ground screw somewhere and see if the image improves.

Hi Wpoll,

Camera has a video cable and a power cable. The video cable has an additional wire besides the video feed. The power cable has + and - wire.

The way I wired the first camera was this:

video cable connects between the camera's video out to the cam video in on the av harness I purchased (see picture I posted earlier)

For the power cable, the positive wire is connected to the 12v wires from both sides of the backup light, as well as to the 12v on the switch box. The negative is connected to the negative from the switch box.

That's pretty much it. The camera works but due to a defect on the lens (mostly my doing), the image aren't sharp. So I purchased another thinking the wiring should be the same.

Anyway, that's where I'm at. I'll report back once I re-wire everything one more time to make sure I didn't miss anything.
