I'm nearly sure I remember this being answered or mentioned before in a thread but I'm at a loss without going through each one for the last few months. I have some dodgy notes scrawled but want to make sure.

So hopefully someone might be able to help out.

The three wires from the Lambda sensor I think are :

Yellow/Red & Black/White are for the heating of the sensor.

White being the voltage reading to the ECU.

Am i right with this? This wire ends up at the ECU in the blue connector block. Think it's actually terminal 65 to the ECU?

I'm unsure as to if I'm right or not, so any help would be greatly appreciated.

Regards

I think you are right in that it's pin 65. I'm doing my 95WRX AFR meter this weekend and I'm guessing the same. I'll probably stick an oscilliscope on it first just to make sure though before I solder the tap on the wire.

Giles,

Can you let me know how you got on with the install after the weekend.

Cheers
