Distributor Cap

I just recently replaced my spark plugs on a Nissan Xterra 2007. I do not see a reference to a distributor cap for my vehicle in my Hanes manual. Did I miss an important step?

Distributor-less system.

No distributor cap for most vehicles these days. Instead you have an coil on each spark plug.

Ok, thanks for the response. I am just used to the older vehicles.
