The location of the OBD port will vary based on model year, but it’s generally found below the steering wheel and above the pedals. It’s usually tucked out of sight, so you may need to get low to the car’s floor to spot it.
In a first generation Ford Edge (2007 to 2014), you should find it directly beneath the steering wheel and above the brake pedal. From model year 2015 on, the Ford Edge OBD port is a little left of that, beneath the headlight controls.
You should be able to spot it once you’re looking around beneath the steering wheel, as it’s the only port your OBD scanner can plug into. It’s a small black rectangular box with sixteen small holes (eight along the top and eight along the bottom).
