Here is the schematic in PDF form.

Things you will need.

1 Short ethernet patch cord

2 RJ45 Keystones

1 4 Pin Aircraft plug

and 1 Box to put it in

I did mine with one keystone and striped the wires on a patch cord no box. Two keystones with a box to accept them will make it more pleasing to the eyes.

This could also be used on many other mics.  Mic Wiring
