Okay we have this

Between shield & White - continuity, opens on PTT close

Black and Yellow does same, cont. then opens on PTT close

Black and Blue open then closes with PTT close (should be TX)

Blue and Yellow - No interaction

Red appears to be Audio

So how should this hook up to 4 pin Cobra? .... which is

1 Shield
2 Audio
3) TX
4) RX

Would it be?
1) Shield & Black ?
2) Red
3) Blue
4) White or Yellow or White and Yellow ?

Thanks for the help!!
