LHD: driver's footwell, under the lower edge of the dash to the left of the steering column, above the pedals and right beside the red bonnet release lever. RHD (UK): exact position on right-hand-drive GLEs not yet confirmed. Start in the driver's footwell under the lower dash near the bonnet release lever, and do not go looking at the passenger end of the dash. Same position on the GLE SUV and GLE Coupé.
Some cars have a small plastic flap over the socket. Pull its bottom edge towards you and it hinges down, no tools needed. If you open it and only see an empty hole, the 16-pin socket has dropped out of its carrier: reach in behind the trim and pull it forward on its loom.
