quick update in case anyone is still paying attention.
got my replacement mini camera (the original i accidentally fried) so , moved the other camera to the rear. problem is that the rear outlet is always on, and I dont want the camera constantly recording and killing my battery.
solution:

You set the cutoff voltage under which the box will cut all power to the outputs. Since alternator voltage is right at about 14v, and battery voltage (depending on battery condition and temperature) is around 13, its pretty easy to tweak to get a setting thats on when the car is on, and turns off when the car shuts off. (the voltage setting may need retweaking a couple times a year though when the weather changes)
here it is wired up. note that I could have significantly reduced/eliminated its footprint by hardwiring it in, and hiding the box in the ample space behind trim panels. but i like this flexibility and it sits out of the way in that cubby. i do need to get some black wire clips though
