Stereo is a little different ...the internal mic is mono Stereo is simply a pair of mono mics (if you care to think about it in that manner) With a mono mic you only have two wires, a simple wire-in-series should suffice ---||||---_O_----- 1.5v mic I believe it makes little odds which side the battery goes on - but it has been about 20years since I last did this. With stereo, the ground will be common - so in theory you may be able to get away with putting the battery on the ground wire. But if you are going for something more serious, then a couple of transistors will be the most plausible solution dujour.
