I just bought my car, it was turbo emanage etc.. ka24de 1993 240sx.I blew the motor up swapped in the same year n/a motor and realized that there is no where to hook up the 02 sensor to? Where would this wire be? I am really confused no cel at idle havent tried driving yet. But I mean there was nothing plugged into the old one I dunno why? If anyone could tell me where to hook It up I can solder and splice no problem,.

This is very urgent because on sunday I have to make a 5 hour trip back home hahah.

Thanks, Andrew.
