I would like to know where the air/fuel guage connects in the oxygen sensor...there are 4 wires on the oxygen sensor...green white black and another black...where does the a/f guage go to it?....

Also what wire do i tap into for my oil pressure gauge and my boost guage... I have a 1994 civic ex coupe.....

from what i've been told, it is better to tap off the ecu for the a/f meter. i didn't like the idea of having loose wires under the car so i went w/ the ecu. as for the oil pressure, you tap off the oil sending unit which is behind the block right next to the oil filter. if you have a mechanical gauge then you would simply use a tee that would simply split the source or if you had an electrical, you would do the same but you can run an extra line from the source to a remote location and mount the oil pressure sensor. for boost, you can get a source from practically anything's that connected the intake manifold after the throttle body. you can either drill and tap a new source on the mani or you can tap off the fuel pressure regulator or brake booster. hope this helps and next time, try doing a search. they are very helpful and some post includes pictures making it much easier. that's how i learned. well good luck!
