I dont get what you mean.

If you are wanting a reading for the AFR gauge you will need a wideband sensor for that. Power for the gauge can come from any switched live.

will be taking a reading for my gauge from the second O2 sensor(the one that goes in the second cat) Been told by mapper that this is the place to take it from.
So need to know which plug into the ecu this is. wiring diagram or something along them lines.

cheers

That will be a waste of time IMO. Far better to get a wideband sensor in there as it will give a proper reading.

Innovate LC1 is what I use - fits in std hole but speak to your mapper to see what he recommends. I am sure he didnt mean use the existing rear sensor.

Hate to show my ignorance but if you put an innovate wide band sensor into the second lambda probe tapping for a gauge then what happens to the sensor that's in there now? Can the signal from the new sensor be copied into the ECU as well as the gauge? Or is the ECU happy to lose the second sensors input? It won't throw a CEL light wobbly if it's not there?
