So i have this problem, i now find out from pre owner of my 1.8 gsr, that he had made custom exhaust dekat and puled out O2 sensor, and from that time it idles rough, and i wanted to wire it back, to got it back to good shape, becous it is hard to drive it, first i was thinking that its and AB or AA version, but i was wrong. So my question is, is there any way to do a new loom for O2 sensor, thanks to all replys, sorry bad english, not use to write only talk 
or some schematics to wire it up to ECU
Yep................here is a wiring diagram for the AC.............just find the plug for the O2 sensor (in the bay, next to the self diagnosis plug, should be single white) and run a new loom to the sensor (in the exhaust)

This thing will decimate all.......once I've put another fifteen grand into it!
Perfect, thanks Bitza you are The Man 
No problems.................Sorry for the late reply. 
And is there a specific distance where to mount it from turbo exhaust flange? or as close as posible?
The closer to the dump pipe off the turbo the better................it will read faster than down before the cat.
Thanks a lot for help

So any help? or idea?
