1. An electrical device configured to provide a sealed connection through a wall comprising: a connector comprising a bore having at least two portions, wherein the connector is configured to be arranged in an opening of said wall and wherein the bore extends through the wall, wherein at least a part of the bore is arranged on one side of the wall and wherein at least another part of the bore is arranged on another side of the wall,at least two electrical contacts each having an end connected to a wiring harness, wherein at least one of said at least two electrical contacts is surrounded by a seal device, wherein said at least two electrical contacts are arranged in the bore, and wherein the seal device is configured to form a seal between the at least one of said at least two electrical contacts and the bore,a holder arranged at an end of the bore for mechanically maintaining the wiring harness on the connector such that, when the electrical device is put in place in the opening of the wall, a junction between the holder and the connector is situated on the one side of the wall, wherein a part of the holder is over-moulded on the wiring harness, on the ends of the at least two electrical contacts, and on an end of the connector. 2. The electrical device according to claim 1, wherein the at least one of said at least two electrical contacts comprises at least one groove configured to receive at least a portion of the seal device. 3. The electrical device according to claim 2, wherein the at least two electrical contacts each comprise an end portion configured to contact with another electrical contact, and wherein the at least one of said at least two electrical contacts further comprises a portion of larger diameter, wherein said at least one groove is formed in said portion of larger diameter, and wherein the bore further comprises a median portion of smaller diameter for maintaining the end portions of the at least two electrical contacts. 4. The electrical device according to claim 2, wherein the seal device comprises a gasket. 5. The electrical device according to claim 4, wherein the gasket comprises an O-ring. 6. The electrical device according to claim 1, wherein the connector comprises a fastener configured to fasten the holder to the connector for mechanically maintaining the wiring harness. 7. The electrical device according to claim 6, wherein the fastener is formed by an attachment of the part of the holder that is over-moulded. 8. The electrical device according to claim 1, wherein each of the at least two electrical contacts comprises in its outer periphery at least one groove configured to each receive at least a portion of a corresponding seal device, and wherein the at least two electrical contacts are maintained in the bore by at least one of the compression of said corresponding seal devices, a force fitting of said at least two electrical contacts in the bore, bonding, and clipping. 9. The electrical device according to claim 8, wherein each of the corresponding seal devices comprises a gasket. 10. The electrical device according to claim 9, wherein the gasket comprises an O-ring. 11. The electrical device according to claim 1, wherein the connector comprises on its outer surface a span configured to form a seal with an inner surface of the opening of said wall. 12. The electrical device according to claim 1, wherein the connector comprises means of joining other electrical contacts, wherein the other electrical contacts are configured to come into contact with the at least two electrical contacts. 13. The electrical device according to claim 1, wherein the wiring harness is connected to a sensor or an actuating unit and the at least two electrical contacts are configured to be connected to a central unit via other electrical contacts. 14. The electrical device according to claim 13, wherein the wall is a crankcase wall of an engine block of an automobile vehicle engine and the sensor is a liquid, pressure or temperature level sensor and the actuating unit is an electromagnetic valve or an actuator. 15. The electrical device according to claim 1, further comprising a blocking means coupled to the connector and arranged on the other side of the wall, wherein the blocking means is configured to contact the other side of the wall to maintain the connector in the wall. 16. The electrical device according to claim 1, wherein the at least two electrical contacts are arranged entirely within the bore. 17. The electrical device according to claim 1, comprising another seal device arranged between the connector and the opening of said wall, wherein the other seal device is configured to form a seal between the connector and the opening of said wall. 18. The electrical device according to claim 17, wherein the other seal device comprises a gasket. 19. The electrical device according to claim 18, wherein the gasket comprises an O-ring. 20. The electrical device according to claim 1, wherein the connector comprises a plastic material. 21. A method of producing the electrical device according to claim 1 comprising the steps of: forming the connector by injection of plastic material,forming the at least two electrical contacts and the wiring harness,putting in place the seal device around the at least one of said at least two electrical contacts,putting in place the at least two electrical contacts in the bore of the connector,assuring a mechanical maintaining of the wiring harness on the connector by means of the part of the holder that is over-moulded, said part being formed by injection of plastic material.
