There's no actual need for the Boyer box positive wire to go to the coil positive terminal at all, as long as the box and the coil both have a 'ground' connection, the double spade connector of the single coil simply provides a convenient junction for the positive wiring, so for a dual coil, connect both items (box & coil) directly to ground.
