looking for a wiring schematic I am looking for a Wiring schematic for the upstream O2 sensors on an 01 vette..
anybody have access to this or know of a place on the internet where I can take a look at this
looking for the pin/wiring for the connectors and to which one they need to hook up to on a aftermarket O2 sensor..
Thanks
Daniel
