Swathdiver, are you gonna add a battery or draw power from an existing source in the tank? I wired my camara on the smoker plug that plugs into the board, since smoker is removed. Pluses are the voltage runs those small 8volt camaras fine, camara cuts on and off with remote when tank is shutdown or restarted, and the smoker off- on switch can kill power to shut it off also. But check polarity on the wire lead or the plug, on mine the black wire is positive and the red is negitive.
