I have replaced my engine in my LR3 and there are 4 wires that I am having troubles identifying. Since I didnt remove the intake on either engine, I wasnt able to get a visual on their destination. Also by looking at the wire diagrams, I am a little unsure if I am seeing that they are infact o2 sensors. Any help would be appreciated.

The plug was chopped on the new motor, so I chopped and spliced the one off of my old motor rater than pulling the intake. Help would be appreciated as there is no way to get the order correct since they are red white red white.

Need to start some where.

 

Pic might help

 

Tom,

Thanks again for your attention. This turned out to be the Knock sensor wires. Was able to trace the wires upstream from the plug and compared the color codes on the diagram. Think that is the last thing on this beast to track down. Been running good so far

 

yeah been laid up, I just got out to the parts truck today to check and noticed you replied glad you got it figured out


for future it plugs into a blue green white brown? that comes out of the harness on top of the engine and sits in a bracket
