Wires are cut and screwed into the RJ11/44. Solder had been applied to the tips of the phone jack mate in preparation for the final union of the Guino to the phone chord.
I still can't find the small plastic piece/metal plugs, and am very apprehensive about soldering directly to the Guino. Radioshack didn't have anything that small to replace it with.
I'm pretty sure that the plastic connector and plugs are gone forever. Where can I find a replacement without buying a whole new MPGuino kit? Spiffle.org doesn't sell those connectors.
