On a 99 there could be one knock sensor or two. Either way there is only one connector. I don't know which cars came with only one, but sounds like yours did.

According to Vida, the S70 base (non-turbo) has the knock sensor option with only one sensor, listed as #10a in Erik's picture above.

Repair info does not specify the orientation of the sensor, but the picture shows it at 6 'o'clock, or with the cable exiting directly down, fed down behind the starter motor bracket and torque to 20Nm.

... your knock sensor codes probably aren’t caused by a bad knock Sensor, either
