are you looking at the diagram in the manual you posted?
because you are wiring it opposite of what the diagram says.
look closely at your mic plug (the black plastic thing with the solder pins on it) and you should see some very small numbers next to the pins/ holes. some have them on the front, some have them on the back (solder side) and some have both sides labeled.
you should not be using the yellow wire.
wire the white wire and the bare copper wire to pin 1.
wire the red wire to pin 2.
wire the black wire to pin 3.
wire the blue wire to pin 4.
an easy way to determine which wires do what on an unknown mic is to use your multimeter set to continuity.
strip back an inch of the cord and then strip off about 1/8" off of each wire in the cord.
there will always be one that is bare stranded/ braided copper wire, and it will always be wrapped around one of the other wires.
the bare wire is your ground/ shield.
the wire that it's wrapped around is the audio wire.
now take your multimeter and put one lead on the ground wire, and the other lead to one of the wires you haven't labeled yet. one of them will show continuity.
this is your receive wire.
now press the mic button and do the same thing again. the wire that shows continuity with the mic button pressed is your transmit wire.
yes, there are always other considerations, in your case, the white wire is also a ground and needs to be wired to the ground pin on the mic plug.
my method is just a way to get started figuring it all out.
hope this helps.
