Lafayette 99-4607 mic to a Lafayette Comstat 23

I recently bought a Lafayette 99-4607 to go with my Lafayette Comstat 23 .

The directions aren't real specific , so there's some assuming going on , on my part .

First it says:

Relay Switching

Shield .... Transmitter or Transceiver Ground
White .... Microphone Input Circuit
Black .... Not Used
Red .... Relay Circuit In Transmitter Or Transceiver

So I'm "Assuming" the wiring code for that would be :

Pin 1 - Shield
Pin 2 - White
Pin 3 - No Connect
Pin 4 - Red

Then...
