Hey all im in need of some help. My friend just bought an air fuel guage for his speed 6. against my advice he didnt get a wideband but rather a narrow band guage. Unfortunatly this means im going to have to tap into the signal wire from the factory o2 sensor. Which wire is it?? Im looking for the pre cat of course, i just dont know what color it is. I looked in the factory mazda wiring book, (i used to be a tech at mazda and still have some friends to give me access to service manuals) and to my surprise it doesnt give a detailed description. Thanks for the help.
