question about wideband install

i just got my lc-1 wideband in today and was reading in the manual that it has an output that can be used as a narrowband sensor. has anyone every installed theirs in the factory front o2 location and used it as both a narrowband and wideband before? i was thinking about doing this if it would work. im sure it would work in one of the rear locations since i have mine deleted anyway, but i figured it would be more accurate in the front if it would work. any body doing this? if not how are u doing it?

no need to pay someone, i am quit capable of welding in the bung anywhere it needs to be, just didnt feel like doing it if i didnt need too. im thinking now i might put it in the rear sensor spot, but does either bank tend to run leaner on these cars, or does it not matter?
