help me out here -

greddy a/f gauge

If I drill a hole in the exhaust and weld a bung or nut in there, I put in the o2 sensor in, then do I need to run the green wire anywhere? Where is it recommended I put the sensor for the most accurate reading?

thanks

I cannot remember what to do with the wire, however mount the sensor atleast 8 inches from the turbine exit.................oh crap u have an S-charger. Mount it as close to you primary o2 as possible

thanks, that takes care of my first Q - anyone know about the green wire that's supposed to go to the ecu? Im guessing I dont have to use it if I keep my stock o2 sensor - anyone know for sure?
