The high temp lambda probe is used to prevent the engine Check LED or pollution anomaly LED from lighting up if you have removed the catalyser or you have installed one that is rather permeable or insufficiently catalysing. It is to be installed on the second probe and does not require an electric system/adjustments/modifications to adapt.
