Hello fellow Mazda enthousiasts,

Since a few months i'm driving a mazda 6 GH station, engine type 2.5, year of birth 2009.
This morning i found a loose connector in the engine compartment.
It's located between the filling points for the airconditioning and the cooling system right at the front in the top side of the compartment.
Has anybody an idea were this connector is used for ?

hopefully this is normal otherwise i'm missing a connection.
I have added some pictures too..
