I've just bought a 2013 GS Prius here in NZ that is a Japenese import. Given it has no USB or 12v accessory power I would like to install a 12v/USB panel. I've seen some Prius's come with a 12v accessory point and heated seats switch in the lower console (under the gear selector). Given my one just has a pocket (see photo), can I assume there may be wiring that is sitting behind there that can provided the nesesary power feed? I have located a replacment panel in Japan that has a hole for a 12v socket and a usb point. Cheers
