One coil is firing corner across to the other corner, and one coil is firing directly above, bottom to top.
If they fire like the first coil packs, two plugs fire at a time, and you could swap some wires around and not have an affect. Meaning that the 1/6 wires could be swapped, because they both fire at the same time, etc.
I don't know the details, just the firing order.
