HISSIN50 said:For the O2 gauge - you can put a toggle switch on the gauge so you can switch between banks and read what each does.
Good luck.

Daggar said:Noooooooo.. can't do that. UNLESS:
You have something else to power the heating element on both sensors. The heaters must be powered when installed in a running motor or they won't last a month.
I'm sure Hiss will have caught that by the time I finish this post.
Edit: Oh wait... we're talking about a gauge on a stock narrow band sensor aren't we? Disregard this post.
st5150 said:This is not true. You can easily wire up both of the O2 sensor's signal wires to a DPST switch and toggle between which sensor you want to read---- but with that said, they'll both more or less read the same and if its one of those red-yellow-green autometer O2 sensor guages, its nothing more than a rice boy light flasher anyways.
