TJ,
Recommend you send the Terra to the local land fill.

Pin-out for your EDO AIR is:
1. Ground (black)
6. Spkr
7. Phones (wht)
12. PTT (grey)
13. Mike (green)
15. + 14 volts (red)

The Edo Air is the best radio around, My crew has one and people turn their
volume down when she transmits with it. Does suck up the amps, though. About 5
on transmit.
Good luck,
JJ Sinclair
