Whats going on guys,

I have an 02 EP3 with a K20A swap, and I cannot get my A/F sensor to work to save my life. I have checked fuses and continuity. I have also replaced it with the oem part. Mods include cold air, clutch, and flywheel. Car idles horribly and smells horrible. Does anyone have the wiring diagram for the sensor receiver that is on the car?
