My 2009 Panda eco 1.1 didn't have a 12v outlet, so I thought that I would install a USB socket where the cigarette lighter would have been. On inspection, there was a three-pin connector underneath the console that fitted the lighter terminals but there was no voltage on it. Next to it, there was the connector for electric mirrors, which had 12v on a couple of the terminals. My car doesn't have electric mirrors, so I cobbled together a connection to the USB outlet, which works. Does anyone know why there is no power to the cables for the lighter socket? The wires disappear into the loom but I couldn't see where they went. The Haynes manual wiring diagram is somewhat confusing. 
Any thoughts would be appreciated.
