Yet another one of those things in the
New Owners Read This section.
Thanks for the replies, fellas. And Iggy, sorry for once again ruining your day with a reoccurring question. I contemplated for about a .3 of a micro second whether or not I should do a search for "what is this wire" or "loose wire" or "holy ****! I can't believe my bike didn't go kaboom" but I've never had much luck with the search engine here - and believe me, I have tried. And, since I didn't know what the wire is, I really couldn't search for the identification of and item I didn't already know - that could result in a universe-ending paradox! No? Well, at least facing two mirrors towards each other.
I did go to the link you posted and found it. My bad. It was one line buried in the 23 page document with no photos. Damn. I just cannot believe I didn't spend at least my morning searching for that rather than post a question on something that - as of now - has been asked 1001 times.
