To correctly place the spark plug wires, you'll need to number the cylinders from 1-8, starting from the passenger side (right side) of the engine and going from front to back. Then, follow the firing order above. Cylinder 1 fires first, then 5, then 4, and so on.
Important Considerations:
* Diagram: Consult a repair manual specific to your 1996 Cougar XR7. It will have a detailed diagram showing the precise location of each cylinder and the correct routing for the spark plug wires. This is crucial to avoid misfiring and potential engine damage.
* Distributorless Ignition System (DIS): This engine likely uses a DIS system, meaning there is no distributor. The ignition coils are typically mounted directly on the engine. The wires connect directly from the coil pack to the appropriate spark plug. The diagram will show you which coil fires which cylinder.
* Plug Wire Routing: Route the wires neatly and securely to avoid interference with moving parts. Avoid sharp bends or routing them too close to the exhaust manifolds which get very hot.
* Spark Plug Gap: Check the spark plug gap before installation according to your owner's manual or a repair manual. The correct gap is critical for proper ignition.
Without a visual reference (a diagram from a repair manual), attempting to wire the plugs based solely on the firing order could result in misfiring or engine damage. Highly recommend getting a repair manual for your specific vehicle year and model. You can find these online (eBay, Amazon) or at auto parts stores.
