Luckily Astatic are amongst the manufacturer's that utilise and stick to a standard colour scheme.
(Some manufacturers seem to use any old wire with a random bunch of colours!!)
Take a look at the link below for the Astatic .pdf file :-
Astatic microphone wiring
The last page shows the standard wire colour scheme and connectivity. All the preceding pages show how to connect their mics to a variety of radios.
If that doesn't help and you just want to know what wire goes where on that 'dang' switch then someone has helpfully posted a series of pictures here :-

Hope that helps.
All the best,
