Capacitor/condenser on back of instrument cluster on a 70 Dart?

Just trying to get a bit of info on the little capacitor/condenser that hooks into the left circuit board of a 70 Dart. The circuit board is bad. I'm replacing it along with the voltage limiter. Also trying to find out the name of this little capacitor, what it does, and see where I can get a new one. I'm having a hard time finding a new one. Any info would be great.
