At work so a bay is tied up right now. I have two white, grey, and a black wire on the rear o2 sensor. My grey wire is the signal wire that I hook up to my gauge correct?

Just really want to get it done before I leave work today.

Sorry if this is a re. HowTo will come later on when I hook up my oil pressure.

Don't know why you only have 3 wires, should be 4.
Also don't know which one you should use.
This is a 2006 2.2?

I have four....two solid white, one grey, and one black.

Yes 06 2.2L.

Sucks only having access to DaimlerChrysler products at my dealership.

 

When installing this wideband O2 gauge with a wideband O2 sensor...where do you install the sensor?

You have to drill out a hole on your exhaust before the Cat. converter. Install a bung (have to get it welded) and screw in your o2 sensor. Done.

 

puttin my aem in tomorrow... I"ll post some pics

 

Well just did the install...after countless tries trying to find someone who knew which wire specifically for the 2.2L(Chevrolet I mean). I installed it and its working.

My A/F ratio is probably around 13:1 or close to that. It's two light brown bars above the two green(rich) under WOT conditions.

I found the wire close to the ECU...its a purple wire with a white stripe.

 

and what about for the 2.0l
