1-5, and 3-7 for the right bank are correct. That's connecting firing order 1,6, and 4,7.
2-6, 4-8 for the left bank is incorrect. That's connecting firing order 5,8, and 2,3 (you dont want two pulses next to each other).
So the correct answer for the left bank is 2-4, 6-8. That's connecting firing order 3,8 and 2,5.
