Connection ?

Does anyone know this is connected to anything? I had a few error codes on my truck? I’ve replaced speed sensor and still have some issues. I wonder if some of these wires are suppose to connect to this. I have a red, black, and white wire that was cut. I connected the black wire (see blue wire nut) that looked cut, but I still see the red and white missing something. Maybe it was connected to something else and fell out.
Something is out of circuit and I’m sure it has to be these two wires not being connected to something.

 

Click on forums, scroll to garage heading, click electrical subheading and locate the wire diagrams there. It should allow you to get it tracked down properly. Good luck!
