wires on oxygen sensor
Okay, on the oxygen sensor under my car on the down pipe, which wire do I tap into for an air/fuel gauge? I think there are like 3 or 4, but I am not sure which one I need to tap into. I have a 94 lude VTEC and it's odb1. Thanks. Also, that copper or brass fitting that is on the passenger side of the block right beneathe the valve cover (I think I can use it for the oil feed line for my turbo) what size AN fitting is that and what should I ask for at the parts counter so I can use it to supply oil to the turbo? Thanks again.
