Under the driver's side dashboard, above the brake pedal. Located in the driver's footwell — reach up and inward from below the dashboard toward the centre of the vehicle. The port faces downward/forward and is not immediately visible at a glance; locate by feel or by looking up from below the dash with a light. No cover.

Under the lower left edge of the dashboard, outboard (left) of the steering column, above the pedals and next to the bonnet (hood) release handle. The 16-pin connector faces down, so kneel in the door opening and look up under the dash edge to see it. Same position on every 2005-2010 WK trim (Laredo, Limited, Overland, SRT8); US Grand Cherokees are left-hand drive only.
Under the driver's side of the dash, just above the bonnet (hood) release lever and to the left of the steering column. The 16-pin OBD-II connector faces downward and is exposed — no cover or flap to remove, it is visible the moment you duck under the dash. Same position across all WJ trims (Laredo, Limited, Overland).
