So I got this car for a steal and I lived in a state where I could get the thing registered. Well I moved to Colorado and now I failed emissions and the O2 sensor has cut wires I guess I never really noticed before. Well I had heard someone talking about Hard wiring the O2 sensor into the CPU and I was wondering if anyone had a diagram on where the wires would go into the CPU. Also what diameter wire should use when doing this or having it done. Thanks everyone.
