Hi,

I'm not sure what you mixed up. Each cylinder has a coil pack and the wire from the coil goes to the spark plug which is below that coil. See pic 1 below

Do you mean you mixed up the connectors to the coils?

I attached a pic below showing cylinder locations if needed as well (pic 2).

Let me know if this helps or if I'm not understanding.

Take care,

joe
