I know, I know narrowbands suck - I'm just using it to fill a hole in my gauge pod so spare me until I get my other scan gauge

Can someone please tell me the wire that I need to tap into for the 02 sensor signal?

You're going through the trouble of buying and installing a pointless gauge just to fill a pod?

 

I picked it up cheap - I want the pretty light show

It's three wires...not all that difficult...so its worth it to me

 

break out your voltmeter, it should have a 0-1v signal and it should dance around alot...
