What are these for?

Hey, as I started to go through the electrical wireing in my Dart, to clean ut a little and try to see what goes where, what is crappy and what goes nowhere and can be ripped out, I discovered these two connectors of some kind (picture) wich was hidden in a large mess of electrical wires taped together.
I checked them and can't understand any function that they might have but there is power to them whenever the ignition is on.
Any ideas what they are for?
