Your vehicle should have the distributorcaps labeled with what cylinder each wire goes to. On the cap, next to each tower, (that the wires connect to) is a letter number combination, example L1. that means if that cap is on the left side of the motor(driver's side) it will go to cylinder number. The cylinder numbers should be atop the valve cover. Both distributor caps and rotors are identical, that is why they have the designations on the cap itself, so you can put them at either side of the motor. Good luck.
