Where can i get a replacement part for my schwinn bike computer? - http://www.k3pgp.org/schwinnmanual.htm

I crashed my bike and the little wire that goes to the left margin. The team is good, but I need a new owner so dark. I can not find a model number, but here's the online manual and a few pictures? How do I get a new media piece in black?
