I have a 2000 Mitsubishi Galant ES 2.4L Engine with California emissions. Installed is a new **federal **catalytic converter assembly. The problem is that I do not know what kind of oxygen sensor to install into the assembly, because the vehicle is from California. I am looking for a solution that requires me to **NOT **replace the entire assembly since the assembly is brand new.

Are there adapters available that convert the oxygen sensor's plug from federal to California?
