Default Voltage on tuned out rear O2's?

Hey everyone
My question is, when you tune out the rear O2's will there be any voltage on those wires?

My second question, what's the best way to physically remove them? I just unplugged them and will be heat shrinking the plug tomorrow. That sound good?

Thanks guys, I appreciate your help!

I just used some zip ties and tucked it to top of tranny - out of site and secure.

LOL!!

Anyway, does anybody know if voltage is still going to flow through the rear O2 wires after they are tuned out?

Yes, all you have done is turn off error reporting

Ok thank you!
I'll be sure to tuck them up so they don't dangle to the ground

Yes.
Just tie them away from exhaust heat and you'll be ok.
On many vehicles you can't pull the fuse because it also supplies other sensors, so you must be very careful to avoid burned wires (and potential short circuit)
