I was installing a wiper switch in the Dart and I noticed that one of the terminals didn't have a plug on the harness. I plugged in the main bundle and the other pigtail with the two wires, but I don't see anything for the lone terminal. What does the lone terminal control? Should it be hooked up?

This is for an intermittent wiper switch on a 70 Dart.
