The right part on the second image? You could opt for building it like the top image, 2 wires either soldered to Alice or make a clip on like the one pictured. In that case you only need a flatcable/VGA connector; should be easy enough to do.
If you want to remake the Video/VGA thingy you'll find it near impossible; or at least very hard to find 23pin D-Sub connectors... Although you could possibly rip it off an external floppy drive...
