That would make it Super simple as long as their socket doesn't have some electrical part in it that's necessary, I'll bet Pier28 would know that for sure since he sells them besides being quite intelligent in these matters also.
Then on the other hand, I'll have to check it and make sure it's not always "Hot"! I have a delay in the electrical system that lasts a few minutes but that shouldn't effect anything will it ? It just lets you still work the electric windows, shuts off the lights, etc.
I also have to keep in mind that when I put the "front" camera in I don't create any problems. Pier28 said to run both cameras you should put in a splitter.
However since I will be running both cameras in "switched Loop mode" only, (no GPS or park mode) I don't think I'll need a splitter.
The Scosche has two USB outlets both treated the same (relative to electricity output) and should take care of both cameras relative to necessary power so I can't think of anything I've missed.
However you know how I am, I know practically nothing about it except don't stick your finger in a live socket, LOL!
