There is a ground that connects the coil to the control module, is that what your looking for?
thats what I got from the wiring diagram on veryuseful.com
It looks more like a resistor type deal but it seems like it's grounded. Part# f6uf-18801-aa. Upon searching the internet it's either a part of the coil or a radio noise suppressor? Can get a pic in the a.m.
It's exactly that, it suppresses electrical noise from bleeding into the stereo speakers. When it goes bad, you can hear crackling in the speakers that can sometimes change when you rev the engine.
