The relays and their pin outs are generic. As spares best to have diode protected 12 volt 40 amp 5 pin relays. Not all applications use the 5th pin which allows changeover contacts but will replace a make/break relay whether it has 4 or 5 pins. Important they have diode protection (quenching) to avoid damage to any associated electronics.

They sometimes come with a redundant plastic or metal bulkhead mount which can be removed since they are supported by the socket they plug into.

Otherwise any good auto spares outlet in France should stock them. Just show them above pic.
