Connector in the first pic is for a soundbar.
Pretty sure the one you’re talking about (not in your hand) in the 2nd pics is the interior OBD port. Later models had the OBD port out by the brake booster, capped off.
To elaborate on the wires in your hand, one is for the buzzer and one is for the courtesy light. One of them will buzz the buzzer whenever you have a key in the ignition and the door is open (reminding you to take the key out - annoying ‘feature’), the other lights the courtesy/dome lights when door is open. If your buzzer has been removed or doesn’t work anymore, then hooking up the blue wire won’t do anything for you anyways.
