try shaft couplers. much like the shaft collars that come with the kit, but a little longer with two set screws. someplace like mcmaster-carr would have these.

check jameco or digikey or a local electronics shop for connectors and crimp pins. you'll have to put them together yourself and they won't be keyed. right now i'm playing with resistors soldered to the legs of leds and just sticking them directly into the holes on the vex. but, you know... carefully.

on the vex, the keyed end of the connector is the signal, the midlle pin is 5v on the a/d and interrupt sections and whatever's coming out of your batteries at the moment on the motor section and the pin opposite the keyed end is ground. i checked it with a meter but the colors of the wires pretty much tell the story.
