It would be my thought that if you cut the ribbon then take some new wire that you have melted the smallest bit of solder to the ends of, you could piggyback the extension wire onto the preexisting connector.
You would then do the same thing to the other side.
Make sense?
Also here is a link to a company that sells ribbon and connectors you could probably just go out and buy a longer one, as an option, (not as much fun).
