If you search you'll find the answer.
Gro Harlem put up a diagram of how to wire them up correctly.

their's 3 wires on your a/f ratio gauge...
+12v, ground and signal.
what I did is I use the cigaret lighter for the 12+v source...I just groud it on a misc bolt.
as far as the signal goes..check your ecu
there's 3 plugs going into it. you want to tap into the middle one.
if you look at the middle plug..you can tap into (one or the other) the one before the last wire on top or bottom (top is front 02 and bottom rear 02). this will be your signal for your gauge
like talon66 said..Gro had a good explaination on this if you didn't get what I said

I think the one I had was:
+12volt was the red wire
ground was the black wire
green was signal. I just grabed the O2 sensor wire at the ecu. But if you just want a simple solution without thinking, just run the wire to the single wire O2 sensor on your manifold.
