1999 Mercury Sable 3.0 v6 Duratec ignition coil pack

Scotty, Either I’m blind or crazy!  The sable started running rough, (after I cleaned the engine of course) so I drove it to parts store to read and pull codes.  Po303 & PO304 cylinders are mis firing.  I’ve done a little research and it leads to replacing the ignition coil pack located on back side of the engine under the Intake manifold.... BUT... there’s no coil that I can SEE????   All the videos I’ve watched, the coil pack is located on back side or to right of block.   There’s no way to over look this part as all the plug wires run to it, NOT on my engine version.  What am I missing?  Is it possible it uses one in a different location?  If so, I’m unable to locate it.    Please help. 

thanks in advance and thanks for all your informational videos!
