If memory servs right yours is coil on plug design.
If you see no spark plug wires, whatso ever then its coil on plug and there is a separate coil for each plug, and it is located right on top of the spark plug.
Pontiac has a knack for hiding other ignition system spark plugs such as DIS plugs are usually under the vehicle way up in the back. You will need a lift.
