   No just that is you took a little initiative to look down a provided   
   path you might get to your desired answer sooner. Or you might come   
   across a reference with a large amount of info such as the Stanford   
   PDF I linked to which came up among the first entries in a google   
   search and shows where the MCC igniter is.

   If you follow this Wiki article on the RS-25 to the MCC section you   
   would see it says the same.   
      
   "The mixture is ignited by the "Augmented Spark Igniter", an H2/O2   
   flame at the center of the injector head."
