I've hit a dead end in my mod. On the lcd screen, an old kogi, there is a little brown "ribbon" type cable with about 21 wires in it. (I was a bit tired, I'll do a better count later) It connects the bottom vertical controller board to the horizontal controller board, but the wire is only about 1 inch and I need to make it about 6 inches.

Is there any simple extender that I can buy? Or am I stuck with making my own? Will just any type of wire be sufficient, or is there a place to buy some already made ribbon cable that I can just solder on? I have never really soldered much before, so for something this small would a 15W iron be sufficient, or something more? Thanks in advance.
