    Do you mean which pairs are on each coil? Or the do you mean the firing order?

    It's not clear to me what you are asking.

    I mean the cylinders assigned to each coil in the pack as they sit in the module as viewed from the front of the car. as read from left to right, or passenger to driver. i.e. coil #1 = cylinders 7-1, coil #2 = cylinders 4-6 etc.

    From the left; first coil is 6 & 7, second is 1 & 4, third is 3 & 8, and fourth is 5 & 2.

    The cylinder numbers are painted on my coils.
