Parking sensors

[IMAY2023]

Hello, can you tell me what number belongs to each front sensor?
I'm making the harness and I don't know where +, - and each sensor goes.
I have the number from the CEM but I don't know what it is.
I follow the xc60 guide

Thank you so much

Look at my previous reply, I enclosed the diagram. 
Basically, sensor pin 1 and 3 are common and pin 2 (middle one) goes to CEM. 
REAR Total 8 wires:  
          SENSOR PIN 1 (common) goes to CEM PIN 15
          SENSOR PIN 3 (common) goes to CEM PIN 34
          SENSOR PIN 2 (beginning from right side sensor) goes to CEM PIN 28 to 33. 
FRONT Total 8 wires
          SENSOR PIN 1 (common) goes to CEM PIN 44
          SENSOR PIN 3 (common) goes to CEM PIN 45
          SENSOR PIN 2 (beginning from left side sensor) goes to CEM PIN 37 to 42.
