FYI Paragon,
As you suggested, it looks like right behind the center I/P outlets might indeed be the best bet. The S212 splice is just too inaccessible.
In the diagram below #17 is where the I/P harness connects to the body harness for the power run for the rear AUX power outlet. Unfortunately, that harness connects on the right side of the front passenger wheel well. So I won't be sure if the harness it's easily accessible behind the center console until I open it all up. At the very least this will be the easiest place to relay one of the front outlets.
Alternatively, I might just try to switch the both front outlets and the rear with a relay right off of the 3040 wire right next to the I/P fuse box.
Now I just need to courage to start snipping.
