Method for manufacturing a wiring system

A method for manufacturing a wiring system, comprising:

• providing an electric cable having an electric conductor and a contact element with a termination portion;
• removing a cable insulation in a first sub-portion of the electric cable, the cable insulation remaining on the electric conductor in a second sub-portion of the electric cable offset from the first sub-portion;
• welding the electric conductor at the first sub-portion to a termination surface of the termination portion, the first sub-portion is pressed against the termination portion and compressed during welding, the electric conductor extends along a first central axis in the first sub-portion and the electric conductor extends along a second central axis in the second sub-portion, the first central axis is spaced apart from the second central axis in a direction perpendicular to the first central axis and the second central axis;
• and
• providing a holding device encompassing the second sub-portion at least partially, the holding device supporting the second sub-portion at least during the welding and compressing of the first sub-portion and maintaining a position of the second sub-portion.
