All these wires are making my head hurt. Can anyone shed some light on how to proceed?
I was informed by my tuner that the AEM UEGO wideband sensor is junk and messing with the readings for him to be able to tune the car accurately. That being said i was told to revert the wiring of the Wideband to the EGR pin and put the stock o2 harness back together. So i follow the wires from the ECU pin 4 and the UEGO has been spliced into and soldered to the wire for pin 4. Easy enough just cut it out and rewire to EGR.. well then i run into the o2 sensor wiring near the ECU... what am i looking at here and why is there bare wire exposed... this cant be how it comes from the factory. Any way to clean this up so i can get the factory o2 set up properly again?
