Pre- 440 swap question

Am trying to think ahead, to when I drop the 440, in my Dart. The Dart was a /6. In the Charger, that the 440 is coming out of, the below pic shows the bal resistor, a two wire silver box and the orange box.
Now in the Dart, I have the bal resistor and a two wire box. I don't think the 440 will run, with just those.
What needs to be done before I put the engine in? Better to do it now, when I can stand up in the engine bay.
Thanks for and help.
