A wiring method allowing connecting an electrical cable , comprising one or several conductive wire(s) , to an electrical appliance , such as a power steering drive-calculator unit , said method comprising: a preparation step (a) during which at least one connector is prepared which comprises on the one hand a first portion, called male portion , which carries at least one electrically-conductive first terminal, called male terminal , and on the other hand a second portion, called female portion , which is distinct from the male portion and which carries at least one second electrically-conductive terminal, called female terminal , said connector also comprising at least one retaining member which allows maintaining the male portion against the female portion so that the at least one male terminal is in contact with the at least one female terminal , the electrical appliance is equipped with a connection box , within which the male portion of the connector is placed, and the male terminal is electrically connected to the electrical appliance , the electrical cable is equipped with the female portion of the connector, and the female terminal is electrically connected to at least one conductive wire , then a connection step (b), during which the female portion of the connector is engaged and fixed on the male portion of said connector by means of the at least one retaining member , so as to create and maintain a weldless electrical junction between the male terminal and the female terminal , then an encapsulation step (c), during which the connection box is filled with a polymeric encapsulation material which covers the male and female portions of the connector so as to form a sealed envelope which protects at least the weldless electrical junction from liquid water. a preparation step (a) during which at least one connector is prepared which comprises on the one hand a first portion, called male portion , which carries at least one electrically-conductive first terminal, called male terminal , and on the other hand a second portion, called female portion , which is distinct from the male portion and which carries at least one second electrically-conductive terminal, called female terminal , said connector also comprising at least one retaining member which allows maintaining the male portion against the female portion so that the at least one male terminal is in contact with the at least one female terminal , the electrical appliance is equipped with a connection box , within which the male portion of the connector is placed, and the male terminal is electrically connected to the electrical appliance , the electrical cable is equipped with the female portion of the connector, and the female terminal is electrically connected to at least one conductive wire , then a connection step (b), during which the female portion of the connector is engaged and fixed on the male portion of said connector by means of the at least one retaining member , so as to create and maintain a weldless electrical junction between the male terminal and the female terminal , then an encapsulation step (c), during which the connection box is filled with a polymeric encapsulation material which covers the male and female portions of the connector so as to form a sealed envelope which protects at least the weldless electrical junction from liquid water. <EOS>
