The right rear yellow wire is wired to the left front sensor which is colour as yellow - yellow. The yellow wire is wired to the instrument cluster. basically they are wired in series. if the yellow wire is open circuit, the alarm will light up at the instrument panel. It have to be shorted to ground in order to clear the alarm. [/QUOTE]
