Where the hell do i find my wire to hook up my air fuel ratio gauge in my car...i dont have any manuals so i was wonderin if anyone knew how or where to find it
sorry i have a 2002 ecotec engine...so help please
just hook it to your oxygen sensor. its the purple wire. and make sure its the part of the wire attached to the oxygen sensor and not the OEM wire or youll get a crappy reading. positive wire you could tap in to your radio wire, and ground is just the chassis ground.
