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 relay20240603_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.

Lastly, the blue wire I am holding in the last pic would be J2, ignition start. This is the wire that is connected to a whole bunch of others that goes to the alternator. I will recomnect it back where I cut it from

So now, the plan is to join the brown J3 wire to the blue J2 wire with a butt connector, and use the cut brown coil wire from that splice as the feed to my relay that will power the fuse block (pic below). The mallory box itself will get heavy power from the battery post of the starter relay

Let me know if this is making sense and would work. I tried to digest everything mentioned here, along with cross referencing my fsm for the wiring. This should give me the power to feed to relay switched in run and start (I hope). Hoping these pictures make some sense.
