Hello.
Has anybody got an idea where the pin in the ecu is for the o2 sensor.
Needing to wire my air/ fuel gauge up.
Cheers.

If you're trying to wire anything into the stock lambda sensor then stop, because it's a ****ing waste of time.

I tried to connect to the sensor in engine but the needle just shot straight round to rich.

Which wire?

The loom side the white wire is a co-ax and the outer shield is earthed.

Direct on the sensor middle wire won't be any different to the wire at pin 29 on ECU.

Outside to wires on connector (blue and brown in loom) are heater, one is positive the other gets grounded by ECU when heater is needed.

As Reckless said, don't bother wiring it to the standard narrow band lambda sensor. It won't work properly and all you will have is some flashy lights that mean absolutely nothing.
