Hello,
I am working on my son's (Turboman23) car. I just had the wiring harness redone (Great work DR Tweak) and need to wire in the o2 sensor. The original o2 had single wire, but new o2 has 4 wires (2 white, 1 gray, and 1 black). Dr Tweak sent a new single wire connector (plug) to wire them together. I can not remember which one of the 4 wires to use to connect to the wire coming from the ECU? Can any one help with this? 2nd question, prior to the new harness, my son's codes showed Knock sensor, he has replaced wiring and knock sensor what elso could cause this? Also CEL stays on all the time. Thanks, Lee This post has been edited by turboman23: Jan 18, 2009 - 5:37 PM -------------------- 1st car- 1994 Celica GT 2.2L 5s-fe SOLD

Are you sure its 4 whites or 5 wires total? I remember the 2 whites was for heating up the O2 if your ECU supported it. The other 2 was for ground and signal back to ecu.
