Searching for 12v switched power after ditching ballast and installing aftermarket electronic ignition

Ok so I think I have this figured out. First pic shows the only wire that comes to the starter relay from inside ignition switch which is the yellow going to "I" for ignition on the relay 20240603_204716.jpg
Next is the brown wire that goesto the "bal" terminal on the relay, that when traced to the ballast resistor, is joined with the coil wire and therefore considered J3 (you can see me holding the cut brown coil wire) and thus ignition start.
That's possible. Sounds vaguely familiar but I can't claim to know for sure. Operationally the J3 is probably getting power when the relay is triggered by the S2.
