Which a/f gauge. Make sure that you keep 12v on the calibration box or the wideband sensor will go bad because it has to be heated at all times. Might be easier to just buy two widebands because the calibration box is what cost so much, not the gauge.

It may even be a narrow band sensor. If it is, I could see how it may be possible to connect a 2 stage toggle switch to the system. Down meaning bank 1 sensor and up meaning bank 2 sensor. This may become helpful in diagnosing a misfire problem as I am having right now. My A/F gauge told me my main problem was my passenger side since my gauge is hooked up to the bank 2 sensor. Could be very helpful to switch back and forth. I may look into this.
