So I'm finally doing a proper installation of the PLX I bought from Thunder550 years ago. And I'm making use of the side view mirror gauge pod that 2007chevy5.3l sold me. (It's art, by the way, buy one!) I have a few questions though, for anyone who's installed a wb in an NNBS. Which pins in the pcm are the positive and ground for a wideband? And does anybody know which is positive and negative on an adaptaplug N? Or do I just plug that into my mpvi and not worry about polarity? Thanks, I'll update the install later.

 

OK, I'll ask a simpler question. Anyone know how I can wire in the wideband sensor in place of the stock narrowband? My narrowband just died tonight I think, so I might as well just simplify. Anyone done it?
