I'm not sure if they'd work, but you can put them either way. They're not polarized. Just try and see if it works.

It's a long time since I last read about these microphones, but I seem to remember that you'd need to put a resistor between pin 1 and 2. A Google should turn up something about them...

Edit: Looks like I just replied to an earlier post.... Think I need to check my cache settings. Bummer...

Edit 2: I think a 0.1uF cap is too small. I know that an amplifier I built used a 2.2uF at the input. And yes, the cap will affect the frequency-curve. It will be a LF-filter, but I can't remember much of the theory. It's about 16 years since I learnt (and used) it...
