Hi,
I'm really a bit stuck with my old bus. It's a 2.0l AAC Petrol and has just failed it's MOT on CO emissions.
Was told that the most likely fault would be the Lambda (Heated O2 Sensor), anyway I thought easy fix... BUT...
It's not connected to anything...
It has 3 wire, White, which I believe is GROUND, another white which I believe goes to the fuse box, and a BLACK wire of which I think should go to the OEM ECU???

Does's anyone have a wiring diagram, or can help on which pin of the ECU this needs to be connected to, as for some reason I don't have any spare wires coming from the main engine loom, but I do have several pins from the ECU that are not connected to anything???

Thanks
