I got some photos of my OFNA starter box. To correct my last post, I use a 4-cell Li-Ion pack to power the starter motor and a 2-cell Li-Ion pack to power the bucking converter to drive the glow plug.
The blue/red wires connect the bucking converter to the banana plug ports on the box. The short black leads from the bucking converter connect to the battery pack. The rest of the wiring ties the master power switch, pressure activated power switch for the motor, and the banana plug charging ports together. It looks more complicated than it is.
