O2 Sensor V70-XC70 1998

OBD code reader says p0133, or O2 sensor error. I can see this sensor on exhaust manifold, but am unsure where the wire connector goes. Can someone tell me where it is, and how it unhooks. Thanks!

    The plugs are attacked from the top.

      Thanks for responding Klaus. I looked at the doc. One picture shows the 2 connectors, black for the front sensor, and grey for the rear sensor. Final picture shows 2 black connectors and 1 grey. There are 2 sensors, why the 3 connectors???
