White's MX Sport Waterproof Headphones pinout?

#1
Hello Everyone,
I have an Excalibur 800 (Old Blue, but not the original Blue) that now has faulty headphones. I have previously done the Peltor upgrade to the phones themselves, but the wiring is now deteriorating. I am interested in wiring up a set of the Whites to replace the current failing set. Does anyone know what the wire to wire connection would be, if even possible? I do know the Excal has only two wires connected to the pcb in the control pod. The Whites has 4 pins. I will be removing the top of the pod and running through the same entry point as the current phones.
Thanks for any tips or tricks!
This would normally have been a job for OBN, but I have not seen him around, and no youtube videos in a few years.
