The diagram below illustrates how to wire a standard stereo headphone plug. The tip is the left channel, the ring is the right channel, and the sleeve is the ground. Use an ohmmeter or continuity tester to determine the channel designations of the solder logs.
With a headphone jack, insert a headphone plug with known wiring scheme and use an ohmmeter or continuity tester to match the jack connections to the plug.
Note: Headphone jacks are sold in open-circuit and closed-circuit versions. The open-circuit jack is general purpose and has 3 pins for the left and right channels and ground. The closed-circuit jack has extra connections for an external circuit, such as a speaker which is disconnected when a plug is inserted.
