Radio Shack sells both a mono Cable [4202420, 6 feet, $4.99 or 4202420, 6 feet, $5.99 (see below for details)] and a stereo Cable [4200961, 3 feet, $1.47]. Date of Prices - 22.Oct.2015.

Option:
Once the Cables are made and tested - OK, consider adding some Epoxy, such as BJ Weld, into the open Ends of the RJ-45 and RJ-12 Connectors, where the Cable(s) enters the Plugs. If you do, let the Epoxy cure at least 24 Hours.
