Passenger side lead on the upstream oxygen sensor melted through. I tried to spice in a section from another DII parts truck. I'm still getting the code telling me that the truck is not reading the sensor. Replaced all four sensors with new Bosch OE. Need to get this damn truck to read the oxygen sensors so it can pass NJ state emissions inspection. The truck runs strong, looks like new, but I can't get it back on the road.
Reading through the forums it seems like the prospect of successfully splicing in the lead was never all that good to begin with. I assume I have to replace the harness all the way back to the ECU.
Looking for a complete, clean, as new as possible, oxygen sensor harness.

I purchased one from Will Tillery this past summer to solve the same issue.

Land Rover made a different types. Check the label where the connections plug into the ECU so you get the correct one.
