Test Harness for Air/Fuel Ratio read while driving.

[peter at thescirocco.com (Peter)]

Since it's a low current signal, the extra length of wire would probably
throw everything off, the extra voltage drop across the wiring, will change
the current. You might be able to adjust for it, but why mess with it... 

Any recommendations on getting a wide band O2 sensors, and displays?

That's what I'm thinking but what I don't know is if it will give any more
or usable data while driving rather than just sitting in the driveway.
