What is this?

Hey guys!
I found this under the dash of my Cuda and it wasn't connected to anything and I was wondering what it is. I found the harness that plugs into it and when I plugged it in nothing happened. Here are some pictures of it. Thanks!

Key or headlight warning buzzer?

It is the headlight buzzer relay. Google the part number (2983872) with the word Mopar and you can find out more about it. The relay may be good. Things still won't work if you have a bad buzzer. It just lets a signal go through to tell the buzzer to work.
