What is this part called??? Help

1971 dodge dart 225 L6 with automatic tranny...
So I jumped the Dart with another vehicle and pulled a rookie move by jumping it BACKWARDS for a split second. Now vehicle has crank but no start but IS getting fuel. Now I have no spark from coil and I think it's due to a part I can't figure out name for. It has a small wire from positive cable going to it then has wires going go ignition coil. What is this or does anyone have any suggestions? On fender well (location)

usually when that starter solenoid goes the engine won't crank at all without jumping the two contacts.


you didn't fry the fuseable link did ya??
