Looking at this further, you must have run another pair or wires to the reverse light as well, which aren't shown on any of your images above, right? This is the source of power and return and it powers the camera AND the decoder? So the decoder needs power FROM the camera, not feeding power TO it...

Makes more sense... but doesn't explain your bad video..

I guess check your connections?
