The distributor cap is labeled for the #1 cylinder and the intake manifold has the firing order stamped on it. The rotation of the rotor is clockwise. Thatís all the info necessary to do the job other than paying attention to details.
You always replace the cap, rotor, wires, & plugs at the same time (every 30,000 miles)
