Location

LHD (US market only): low on the driver's side of the instrument panel, under the lower edge of the dash below the steering column. It sits out of sight from the driver's seat, so crouch in the driver's door opening and look up under the dash, between the column and the door-side end of the dash where the hood release handle is. Standard 16-pin DLC. Same position on key-start and push-button-start trucks.
