    You wouldn't happen to have info on where to buy the pins for the wiring and which pins they are, would you?

    yes some of the later GM stuff in the US works off O2 sensors... the latest stuff in Aus works off a sensor.... it will all depend on the OS to what you need...

    Interesting would be great to be able to have the PCM determine the amount of ethanol in the fuel either by a sensor or with the O2's (this could be a little harder for those with longtubes since the readings are a little off) and have it change the trims accordingly
