However, to be absolutely certain about the coil pack's cylinder number arrangement, you should:
* Consult your engine's service manual: This is the definitive guide and will have a diagram showing the firing order and coil pack arrangement.
* Look at the engine itself: Some coil packs might have the cylinder numbers molded or stamped onto them.
Remember, the firing order can affect how the cylinders are arranged on the coil pack. While #1 is consistently on the passenger side front, the order of the other cylinders in relation to it on the coil pack follows the engine's firing order. A service manual or diagram is your best bet for precise identification.
