are 2005 and newer factory O2s widebands? to hook up a guage, the only thing needed is to tap an O2 wire?

 

Not that I'm aware...

 

Yes, 2004+ have wideband o2 sensors - but I am not aware of any way to simply hook a gauge to them. Nissan scan tools such as Uprev Cipher are able to decipher it in some cases, as well as the Haltech standalone. The stock widebands are primarily accurate in the 13:1+ AFR range, so they are not great for boost tuning.

 

thank you

 

i think this is the idea you have.....don't bother,just go buy a wide band

as Hal said, to moniter properly, you need a dedicated sensor and display
