can I attach the a/f reading wire to either ther driver or passenerger o2 sensor, which color wire to attach to the GM o2?
the only hole I see to go from inside the car to motor area is right behind the pcm is this the only way ( where there is allready a hole?

purpose of this install. can I plot my fuel curve ( basically observing the richness or leanness at certain RPMs so after I add my Long tubes / catted y-pipe if it's pretty close don't bother with a tune, dynotech states direct bolt on replacement and they have the rear o2 bungs for the rear o2 sensors.

Lastly the a/f ratio meter is only a tool and should it be removed after all changes to motor have been made.
I'm thinking the meter is sucking up power that really should be going to the PCM and if it stays installed all the signals that the PCM reads are not exact?

Thanks to all reponses

I installed mine precat in the passenger leg, and routed the wire through the shifter boot under the console.
