If you do not have the book try this....
Make yourself a test mike jack for the radio--short wires with gator clips on the ends. Use different colors to denote different pin numbers. You will be using these clips to make temp connections.
Short out the clips on the test jack in pairs unill you find the pins that key the radio. Using these two clips and the black wire on the mic find the other wire that JUST keys the radio and that is all. You now have the keying.
Using the remaining two wires (I take it that you are using a 4 wire mic.) and the remaining two wires on the test jack experiment with wire position so as to get your audio going. MEMO: some 4 wire radios do not use all 4 pins. If merely swapping the two wires around using the unused wires does not work then using one audio wire at a time touch it to the key wires (one at a time) Some radios use a common ground for both mic and key. An easy way to tell this is by taking off the case and looking at the pins on the mic plug. If one of the pins does not have a wire attached then you are most likely looking a a common ground situation.
Once you have acheived audio on keyup you now have your wiring configuration.
Now you have audio AND key. Note which pins the wires go to. Solder away. Note I stated WRITE IT DOWN. Never trust your memory.
This trick has never failed me with 4 wire mics.
If the mic has standard colors you might check the D104 web site for their color pin charts as a starting point.

Cobra,
IF this is a mic from a Northstar radio:
Wiring should be:
Pin #1 ~ Shield & Common
Pin #2 ~ Audio
Pin #3 ~ Transmit
Pin #4 ~ Receive

Are they still hooked up to the Mic 4 Pin Plug?
If they are it is probably the same wiring for the Cobra/Uniden Mics and Northstar radios.
As for colors I have no idea what they went to from the factory.
Sorry
