Or in other words, the most forward cylinder will have the #1 spark plug wire which would go on the distributor cap where the rotor points to that position when the #1 cylinder is top dead center. The # 2 or second inline cylinder wire goes on the dist cap in a position four away from the #1 wire (counter clockwise direction) etc. etc. according to the firing order. The position right next to #1 on the dist cap is where spark plug wire 5 would go.
