It's another locking system with an internal bar with the pin slots that is unlocked when you remove it from the exterior housing, much similar to the connectors used on the BCM, if I recall correctly. I've spent a much longer time trying to discover how to reach the door disconnector in the A pilar since the diagrams I had weren't clear and I couldn't find any access from the footweel to the pilar interior area (I even removed the front wheel housing liner while trying to find it!), until I eventually discovered that there is a small square hole covered by the hood release lever mount. After releasing the clip at the exterior side at the bottom of the connector, remove the hood release lever mount and you will be able to remove a piece of foam and pull the connector by its harness. Putting it back is a little harder because the hole is too small for a hand to pass and you'll have to put the connector in place by holding it from the harness, but you can do it with a little patience.
