I think I found 12v Sw right where I need it!
In the center console area there is a unused 4 pin connector, that I think is for the phone option. This connector has both 12vBatt and 12vSw. The RD/GRN wire is 12vBatt (continuous) and GRN/BLK is 12vSw (Switched). Checked it with the DVM, and confirmed.
Now I can just wire from right there...
