Thanks Benzmac....I've found the signal (1) and heater wires (2). However, it seems that the hole from the passenger sub-floor leading to the oxygen sensor is quite small...I don't think the heater wires (with the plug) will pass through the hole....

Also, is the other end of the wires directly connected to the oxygen sensor?

How do I check the Lambda?

Thanks.
