Method for adapting a wiring harness for a motor-driven land vehicle

A method for adapting a wiring harness for a motor-driven land vehicle in order to allow, without cutting or splicing, connecting said wiring harness to a computer system that is configured to be temporarily and removably mounted on board said motor-driven land vehicle, said wiring harness comprising a first connector, which is provided with at least one first connector socket, in which a plug is removably housed, arranged at one end of an electrical wire, and a second connector that is provided with at least one pin (6), said second connector being configured to be connected to an electronic control unit of the vehicle, the method comprising the steps of:

• removing the plug of the first connector from the first connector socket to thus leave the first connector socket temporarily vacant,
• procuring a booster connector comprising at least one booster connector socket formed to removably house the plug of the first connector and at least one electrical wire provided at one end with a first plug formed to be housed within the first connector socket, the other end of the electrical wire of the booster connector being connected within the booster connector to a second plug,
• inserting the plug of the first connector into the booster connector socket, and
• inserting the first plug of the electrical wire of the booster connector into the first connector socket left temporarily vacant after the plug of the first connector is removed from the first connector socket.
