Default 2.5 Ignition System Description/Components

I've been "Googling", Searching for an hour trying to find a simple "description" , or diagram of the 2.5L dual ignition system--to no avail.

Primary Coils, Secondary Coils---How many Coils are there, and to which plug/s, and in which Cylinders, and which bank/side to they "connect" to ?

All I seem to come up with are Mods.
