I have 2 older K-line F7s that both seem to run with a wire connecting them like a steam engine to its tender. Only problem is my F7s just do not have a connecting wire, its obvious where the wire should go because of the holes in the rear doors of each unit. I opened the units and in the rear unit the one without the TMCC boards or sound unit it has a male 10 pin cable 
and In the front unit I found a female 10 pin.
I put them on 2 tracks side by side and connected them and they run perfectly in sync but the wires are obviously not long enough to reach across the units.
So obviously I am missing some kind of connecting wire of course K-line doesnt exist anymore I cant get a replacement wire not that I would even know what to search for. I was wondering if I could use a 10 pin cable (or whatever that wire is called I m truly not sure what its called) in between the units and just not be able to separate them but atleast have them running. Or if anyone knows if I could find a replacement wire if anyone is selling them anywhere or what to search to find them.
