Ah. 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

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.
