Open the hood at night in a dark area and start the car. If its jumping out of the wires or coil someplace you will be able to see it.

Update:
Last night poped hood saw no arcing anywhere did the water bottle trick....I remembered I kept old one, swapped out old Ignition coil no buzzing or ticking. Never came across a very loud one? Bought it from rockauto did a warranty replacement.

Yeah, it's possible the coil had insufficient insulating fluid in it. That would allow arcing inside the coil that would sound like buzzing. Good they swapped for you. Problem solved?

Well got a new from rockauto in the mail. How COW this one is louder then the first one? It's just a OEM Ford part. On the box it says made from Poland...I really don't see that being a big deal. My stock orignal one is super quiet! I wonder if this is normal now? I'll try to get a hold of rockauto customer service. I've bought from them almost 7 years never an issue? Maybe I'll just keep the old one in.....

I've heard of loose spark plugs causing this, where the noise was a symptom of spark taking an alternate path (one of least resistance). I would ask you to double-check all ignition-related electrical connections, but the way your old coil still seems to work quietly suggests that you've already narrowed it down.
