I have a piggyback fuse connector and am looking for a fuse in any of the fuse blocks that is only powered when the key is in the on position. This is for powering up a backup camera. I originally spliced into the radio power but that was a bad idea (popped fuse, wiped out memory, etc.) So I'm trying to go a cleaner route. This is for my wife's 13 V6 base, thanks!

edit: This should have been posted in general, but the wiring is basically the same between my GT and her 6'er.

 

I did something similar, hard wired my radar detector. I found an unused tap in the fuse box that turned hot with the key. Works fine.
