I just recently purchased a 03 disco with 80k on it and the previous owner replaced the cats on it but cut out the precat o2 sensors in the process. I'm having new sensors installed but they cut the harness off where the sensors plug into so i'm going to have to hardwire then sensors in. Anyone have the color codes for the wires to do this?

 

I would try to find the connectors at a salvage...

The RAVE Manual is in my sig. It is a free download.

This should get you started...

C0642 and C0643 are similar, and so are C0644 adn Co645
