Warning light Airbag/SRS

I had the SRS light constantly on and turned on when I had pushed back the steering wheel height adjustment a little bit. Today I had the error read out and reset and according to Tech 2 the trigger should be one of the two pears in the pictogram. Since I still have a cluster instrument from my old 9000er, I looked at it the same time and found that there are really two pears, one with gray and one with black socket. All the other pears also have the black socket. Has someone ever dealt with this problem before? I would expect that the same pears can be used for both slots, but would like to hear the opinion of the experts again for safety. It is also interesting that these pears are not connected in parallel, for example to the failure safety. At each pear two separate ladder lanes go, which is also well visible on the switching plan to the pictogram. The one pear gets its signal directly from the airbag control module. But where does the other signal come from? Can someone help me, because I don’t want to fix the problem in the airbag.
