[Mk2] [Turbo] O2 Sensor Wiring (In downpipe)

[UniSol]

I have just bought a Oxygen Sensor from RogueSystems.

New O2 Sensor is wired as below:

White - Heater
White - Heater
Black - ECU
Grey - Earth

Wired into the Toyota wiring plug:

Black (assumed Heater)
Black (assumed Heater)
Blue (assumed ECU)
White (assumed Earth)

Please could someone correct my Toyota wiring detail?

My car is over-fuelling at present, with the above wired.

the 2 blacks are heated but then you knew that anyway. If the car is overfuelling swap the other 2 wires and see what happens. I found the generic O2 sensors didn't work on my rev3 so I ended up buying the org Toyota part. It's still cheaper than rebuilding a blown engine
