The plastic MMJ connectors are a current item in many parts
catalogs, such as Parts Direct and Specialized Products. As far as a
walk-in store near NYC, Electronic City in New Hyde Park, Long Island
has them at the back counter.
The plug is simply crimped onto a flat telephone wire (6
connector), just as you would do with an RJ-11 or RJ-45. Some of the
better (ratchet type) crimper kits come with a set of dies that
include MMJ. Cheap, simple crimpers have a 'one size fits all' hole
that will work surprisingly well, if you proceed slowly and
cautiously.

Print it out, take it to Electronic City and have them make up
some cables while you wait.
