Some mice chewed up the wiring of my 2005 Ford Taurus. I have already replaced the spark plug wires, but I need help identifying the remaining wires and the parts to which they run.

Here's the first photo:

One of the wires runs to this, which has part number XLIF-18801-AB PBT-GF30. From the research I did, this seems to be a "radio interference capacitor". Can anyone confirm this? If it is, it seems inessential. Is there any danger in driving without fixing it?

Here's the second photo:

I can't seem to figure out what this part is. Does anybody have any idea? 

Ideally, I'd like to try to splice in new wire, but I'd like to at least know what system I'm splicing into. Any help identifying these parts would be much appreciated.
