That white round thing that you removed from the hub is the Horn Contact Spring and Bushing. That contacts the Steering Column Upper Bearing. The wire that is exiting the steering column is connected to that upper bearing. You should have continuity between the face of the bearing that you can see thru the hole in the wheel hub and that loose wire exiting the steering wheel. You may have to pull the wheel to get access to clean the face of the bearing where the Horn Contact Spring rides.
