Elite Pro - Optics Edition Jack Wiring Diagram Needed.

I have the Turtle Beach Elite Pro Optics Edition Headset. The jack bent and doesn’t work now. Upon splicing the cable to replace the 4-pole jack, I found there’s only three (3) wires. Confused!!!! How do I connect three (3) wires to a 4-pole jack?
