Hey guys i have a NGK/AFX wideband that im trying to wire up to my new LS3.
question is where should i grab power?
i have been told use the rear O2 for power and ground seeing that i no longer run the rears, and hook into the EGR plug for a signal back to the PCM.

my prolem with this is that as far as i know the rear O2's only support about 5 Volts,is this enought to power the unit?
