I think it is the following.

from front of car looking toward windshield,

cylinder closest to radiator is #1 increasing to # 4 closest to windshield.

Looking at ignition coil from front of car toward windshield, going clockwise

starting at bottom left is #1. top left #2, top right #3, bottom right #4


I think that is correct.
