prosport wideband install

i bought a prosport wideband and was told by prosport i could run it off the same o2 bung as the rear o2 sensor. so the wire off the original o2 is going to be left unplugged? does this sound correct?

Yes that is how I installed my WB. The only thing with leaving the rear O2 unplugged is that it will throw a CEL. If you have dsmlink, you can disable the catalytic check.

thats what i was thinking. yes i have dsmlink. so in the end the o2 sensors arent even needed as long as you can ignore the code.

also did you reuse the old grommet from the old o2

yea the rear O2 is just there to check the cat efficiency. I didn't reuse the grommet, since the plug is huge, I barely got it to fit through the floor board.
