how to wire tether kill switch

the way i have my tether on my quad is that their is three other wires in that strand with the clip for the controll box... there is two white and black striped ones and just a plain black one.... the plain black one is for the gound so put black on black for on wire...... then put one of the black striped wires on your left over wire for the tether..... their will be one wire just hanging around....
