There is not one. Lay out the wires by length. Then just determine which one fits the best. The image is the firing order. Start with the shortest wire, it will be cylinder three, the next longest goes on two, then cylinder one and four last with the longest.
Normally you would remove the wires one at a time and match the length as they come off.
