I am installing my Air/Fuel Ratio meter and have come to the part where I connect the O2 sensor. I have a white AE800 ECU but cannot determine where to connect. Looking at it there are 3 plugs down the left :- black at the top then grey then blue. Most of the wires have silver dashes on them and there appear to be several white ones (with a stripe of another colour). Which plug is the O2 sensor in and which wire? Can I remove the plugs with resetting the ECU and if I do will the No. 21 be printed on the bottom end?

Thanks. But is it the front or rear O2 sensor I am looking at. Also are these diagrams relative to the UK spec cars.

Can I just remove the plugs and will they have the numbers on the bottom?

Also, all I read is that the AE800 is black. Mine is definetly white. ???
