Lay both of the oxygen sensor next to each other so the
sensor housings are the same level. |

Tie the excess length of the sensor (approximately 50 to 250
mm) back so it is the same length as the faulty sensor and
secure it with cable ties -1-. |

Check if the oxygen sensor connector housing is compatible
with the vehicle electrical system side. |

If necessary, replace the vehicle electrical system
connector with the provided oxygen sensor connector housing.
