Brian, welcome to 2CarPros. Might I ask what the vehicle and engine is you need the plug diagram for? If it's an 02 Intrigue with the 3.5 in it. See the attached. No wires are used as this engine is coil on plug with 3 coils attached to the cover on each side. It's basically the V6 version of the Northstar engine used by Cadillac. Good engine as long as it's maintained.
