Under the left side of the dash in the driver's footwell, outboard of the steering column, just above the hood release lever. The 16-pin connector is clipped into a cut-out in the bottom edge of the lower dash panel and faces the floor, so look up from the footwell rather than from the seat. Same position on every US 2008-2012 Accord sedan and coupe, 4-cylinder and V6, either side of the 2011 facelift; all US cars are left-hand drive. If it seems missing, look for it popped out of its bracket and hanging behind the lower dash.
