Missing harness?

I think I have a missing harness? So I was taking my dashboard apart center console where the switches are or where do the plugs enter the main harness? I cannot find two plugs!
I found that one switchbox was not even connected. When I was looking for the two plugs I could not see where they joined the main harness or maybe they have fallen further than I can see?
But can anybody tell me where the switch box connects to the harness? this switchbox has the mirror heat, sleeper temperature and sleeper fan Engine brake range 123 PDL lock and suspension dump switch’s

 

OK so maybe I’m not crazy
Would you say that there is but one harness since they are all similar that goes harness into switch pack out of switch back into switch pack like this
