Would it then be the Spark Electrode? I just finished rewatching the video from Mod 7 unit 3. The spark electrode is what generates the spark at the burner head to create the flame, if i am not mistaken.
After looking back at the schematics / wiring diagram, I believe the part I am looking at is the “Spark Lead” which is what is attached to the Sparker Wire and to the Spark Module.
