As I'm from the US, I'm afraid I won't be much help in identifying the terminals, but would suggest that it might help someone closer to you and more knowledgeable regarding the connectors used in cars there if you post the year, make and model of the vehicle in question.
With that info, hopefully someone can help to identify the part. Be forewarned that the terminals may not be readily available, as car makers (at least here) tend to use a lot of specialized connectors made just for them, rather than normal 'commercial' stuff commonly available from electronics vendors. GM, for instance uses a lot of 'weatherpack' connectors.
Good luck in your search.
