The wiring for this microphone is,

Shield= GROUND
White= MODULATION
Red= PTT
Black= RX
Blue= Switching ground (may need to connect with ground on some radios)

Look at a schematic for the radio to see the pinout for it, my guess would be the black wire won't need connecting.

there is only 4 wires on the para dynamics, black, shield, red and looks like pink or lavender color

Okay, to check the wiring use an ohmmeter to check what color wires are the PTT and RX or remove the bottom plate and see how the switch is wired, at the same time look at what wire would be modulation. If it runs to the switch it probably disconnects on RX.
