To clarify things a little: All resistor values listed above are to be connected between the tip and sleeve of the 1/8" plug (stereo headphone plug). Apparently the only use for the ring is that if you connect it to the sleeve the "Seek" buttons cycle through radio preset stations rather than directly tuning.
Do NOT connect 12V to anything!!!
