3 pin plug next to the ECU connectors

[LeedsMike]

Dont suppose anyone knows what the 3 pin plug does that is attached to the ECU wiring harness?

Have had a quick look through the wiring diagrams and cannot put my finger on it.....

Thanks!

As you have an S2 I can only make a guess that it is for the CO Pot which wouldn't be fitted to a car with an O2 sensor from the factory.

Those of us with an SE that has had an O2 sensor fitted and a closed loop ECU will have an CO Pot, and I can't see a 'spare' socket on my car.
