[TenTec] Shure 450 Ten Tec Setup Question

[OTAKEBI at aol.com]

I found a Shure 450 and would like to hook it up to my OMNI V.
It came with no spec. sheet or documentation.
Wires in original cable are red, white, green and black and shield.
It looks like White is mic and should go to pin 1
Red is PTT and would go on pin 3.
Shield is to go to pin 2.
Now I have Black and Green left.
One of them I think should go to Ground pin with shield and the other I  have 
no idea but it might not be needed.
How far off am I and could anyone on the list guide me in the right  
direction if I called it wrong.
Also, has anyone used this mike on the OMNI V or Corsair II and did you  like 
it?
Thank for any help,
Dan/N4VET
