RHD (UK): driver's side, outboard of the steering column, level with your right knee. The 16-pin socket sits behind the small pull-off cover in the lower dash panel, right next to (on the left-hand side of) the interior fuse panel, so you see the fuses and the socket together once the cover is off. Same position on Trek, Sport, Aventura, Acenta, n-tec+ and Tekna, pre- and post-2010 facelift. LHD: the mirror image, under the steering column at pedal height, above the pedals on the left side.
Pull the small cover by your right knee straight off. It is a push-fit flap and needs no tools. Behind it are the fuse panel and the white 16-pin socket. The socket is right there, with no reaching behind trim.
