    The best place to connect your A/F gauge is at your ECU. You can simply place a vampire tap on the signal wire feeding the ECU.

    This signal wire connects to the B17 pin on the ECU (see diagram if you're having trouble).

    If you're having trouble locating the correct wire check out this site for a bit more information:

    Hope this helps.

    Ohh...my bad. I didn't check the model year of your car. I'll see if I can find an ECU map for your car.

    Sorry about the mix-up.
