One end goes to ground, the other to the cap.
If its electret mic, connect the positive terminal to + via 10-22K resistor.

the mic thing
well, i can see where the mic would come in, guy, but i wouldn't connect the mic straight to the circuit. I'd at least use a preamp the the condensor mic. This can be done quite easily with a 2n2222 or 2n3904 npn transistor. Take a look around the net...you'll find some basic schematics on electret preamps. Basically, from the npn's collector, you'll connect that to the audio input of this transmitter.
