Bug Start Stop Volvo V60

Moin moin love moose community. I have the following problem with my v60 bjr 2013 2.0T 163 ps. And though my start stop does not go since I own this vehicle, because he has a mistake with the BMS. Then I looked at it all today and saw that there somehow a cable and a plug is missing. I don’t know why or what the predecessor did but somehow that’s what lazy. I would like to know where the cable goes with the plug to see where the with me is.
