[TenTec] Corsair II Shure 526T Series II Setup Question

[OTAKEBI at aol.com]

Have a Corsair II that I want to hookup to a Shure 526T Series II.
I think I need to set it up for Grounded Switching.
If so, I have the following information available to me.
Corsair II pins are as follows:
#1 MIC
#2 GND
#3 PTT
#4 +V FOR ELECTRET
Mike wiring information is as follows:
Black=No Connection
Blue=Ground
Red=Transmitter
Yellow=Loudspeaker Ground
White=Audio
Shield=Ground
I think that:
White should go to pin #1
Blue and shield should go to pin #2
But, Should pin #3 be Yellow which is Loudspeaker Ground or Red which is 
Transmitter?
I know pin #4 should have no connection since this is not an Electret Mike.
Thanks for any information.
