Which O2 wire do I tap the green sender wire to?

 

You realize this gauge is essentially pointless correct?

Anyways, it needs to go to your primary (bank 1, sensor 1) o2 wire.
It is purple and white.

 

Why would u waste ur money on a narrow band? U like having a light show in ur car that tells u nothing? Ur car has wideband, u should have invested that money into something like an intercepter that will read the wideband sensor

 

Assuming his profile is correct then no, it does not. Well, unless he has a super rare and unheard of 2005 LNF....

 

Oops just assumed he had lnf. My bad lol still waste of money though

 

Thank you for the help and tom my lsj isnt wideband.

 

Ya I was corrected lol though it was lnf

 

buy a wideband guage and o2 sensor, narrowband is next to useless.
