Shield goes to pin 1.

The shield is wrapped around one of those wires. That one goes to pin 2. Probably the white wire.

This leaves red and violet. One of them is transmit, the other one is for receive.

Check for continuity from the violet wire to the shield. If you see a circuit between those two wires, the violet goes to pin 4. That leaves the red wire for pin 3.

The wire colors found in a mike cord are frequently just arbitrary. Using a meter to see which wire has continuity to ground for receive and which for transmit will sort this out.
