[Yaesu] Info on wiring mics for the ft-847 ??

[A10382]

Does anyone have any info on wiring popular desk mics (i.e.; Shure, Turner,
etc) for the ft-847 ??  I believe these mics originally came with a booklet
describing how to wire the mic for many popular radios.

A web site with info would certainly be a welcome reference.

I do have a Shure 450 desk mic.  Despite being rather old, it appears to be
unused. However, it came wired to a 5 pin plug.  It has a HIGH-Z / Low-Z
switch.  I believe the LOW-Z setting is needed for new rigs like the -847.
???

Also looking for sources for the Yaesu 8-pin mic connector plug (mic end).

Thanks and 73
Frank
