On my mic (serial #14785), they go like this:

1 - white
2 - black
3 - blue
4 - NC
5 - red
6 - brown
7 - braid
8 - NC (center pin)

As you can easily see, there doesn't appear to be any hard/fast rule to
the color scheme or to the number of conductors.

best thing to do is to use your multi-meter

select each wire in turn and look for continuity
these could be the rx wires , next key up and see if the
signal on the meter drops , if so they are the TX/ox -ppt , or one is
and the other will be the gnd , one you know the ground
work around the others , to find the wire that produces
about half scale of the multi-meter , this is most likely
the audio/ or mic wire , now you know 3 wires
its getting less and less for you to have to work out ,
I presume the others must be up & down buttons
and maybe a separate voltage wire .

use the meter or try to look at the radio cct
this should tell you all the info you need to know .
