I have to hand it to you guys, you are a mine of useful info to many on here, without your help many would be struggling for ages. Useful helpers to know.
if you don' mind me asking almost a year later, where can I find something like this. I have a 2004 LR Disco and my O2 sensor harness needs to be rewired because of the previous owners crappy splicing. I don' even know if the wiring is correct. I looked on the rave manual but can' seem to find the correct colors coming for the harness. 2 wires from the harness match with the connector which are the blue/white & Brown/orange I think. But the other 2 from the harness to the connector don' match. They had the green wire from the harness spliced to the red/black coming from the connector and the red/black from the harness connected to the yellow on the connector. I' almost for sure they changed the connector out probably because they broke the original. Before I splice the wires together I want to make sure they'e connected property. I did check voltage on the wires with the ignition switch on. I only have voltage on the brown/orange and blue/white. The red/black & green wire were dead. Anything would help. This is for the O2 sensor on the passenger side after the cat.
Cool. I know what a PITA it can be to fix a boogered up wiring job. Good Luck!
reason I was down there and just plan on replacing all 4 is because obd reader says there' no activity on all 4 sensors and I have open/circuit on 2,4,6,8 injectors. A couple other things as well but I think I need plugs and wires. But this is an awesome diagram. Where did you find it?
Ok so i finally got around to trying to fix the harness but i cant find in the rave what color pin goes where. So if anyone can help me out i would appreciate it.
Btw i know you cant really tell the color by the pic but i can by following the wires further up the harness.
Same issue. I went to change all 4 o2 sensors and the passengers upstream harness pulled off exposing all the pens. I am going to attempt to connect it using these pics. Ever sinse its been running like crap and misfiring. My mechanic said that he fixed it but i am getting way more fuel mixture, misfires, and Lamdba codes now. I also got the code that the upstream sensors were swapped. Arent the 2 upstream the same? Any advice is appreciated.
