Not to complicate matters further but this attachment also went bad soon after I bought my black car, so I had to replace that as well. That was a pain in the crotch, difficult to get at connections in a cramped space under the dash. But even with me being a short tempered rookie I was able to change that out too. The experts here have great guidance. Later along the way had to replace the salve in the engine bay too due to grinding/internal slave going bad; got a long throw when replaced that.
