    so transfer the wiring/vac. from the 'stock' one, to the new one..
    A/F gauge.. well, if it's a narrow band AFR, then it's #1: worthless, #2: worthless, #3 neat to look at for about 2 minutes.
    There's usually 4 wires.. red=12vdc, black=ground, white=illumination, green or purple or gray=signal (tag this to the OE oxygen sensor signal wire.

    if it's a wideband setup, that should be left to a professional, if you're asking.. It's not hard at all, but..

    i have a wide band O2 sensor so does it matter if it is a norrow band A/F guage. it says "real-time level measure on your vehicles air/fuel ratio

    yes, it matters..
    narrow band readings are in the range of 0v-.9v
    wide band readings are in the range of 0v-5v

    so you can see where it wont work.
