Its a 3 pin connector, on mine, it goes;
blue to white/brown
left black to red/green
right black to black/red
This is looking at the connector with the blue wire uppermost.

But I have shielding over mine, so the left/right designation only applies at the connector end; it may actually be the other way round at the sensor end.

2 black wires are for heater and have no polarity, blue wire is for signal

Cheers oldcorollas, on that note, from my 1g diagram, it has what must be the two heater wires, coming from the main efi relay, and the other from the HT pin on the ecu (which i'm assuming is heater).
Why does it have two inputs for the heater?

so one wire is direct from the EFI relay and must be +12V??
it may be that the ECU controls when the heater is on and off, by means of 'closing' the heater circuit, ie grounding the heater.
the heater would not have 2 positive power inputs.
the third wire goes to Ox or similar on ECU?

Ah yep thats probably it, the ecu switches the HT pin to ground so current can flow through the heater. I get it now, I didn't think of that 
Yeah, the third wire goes to the OX pin.
