hi hope some one can help i have a xc with a EL engine fitted. the problem is i cant find where the wiring was cut for the O2 sensor as the wiring has being moved so much from the original EL layout . i purchased the car un reg went for blue slip got knocked back on the O2 sensor not working.I have a new sensor,both plugs,plus around a foot of wiring.is it possible to rewire it from scratch.I think one wire is earth one goes to pin 29 no idea where the other goes any help would be useful maybe a wiring diagram thanks Howard

29 is signal wire, 49 is earth, other wire is just ignition 12v to operate the heater for the sensor, from memory.

sounds good Thanks
