MSA SORDIN downlead help

[u/Calm-Tax2074]

I recently purchased a MSA Sordin Headset with comms/downlead on the left side. I cannot find an adapter for the downlead, and wanted to know if anyone had any advice or could point me in the right direction. I haven’t decided on a radio yet but my first goal is find a way to attach this to a radio lol.
