Alright so on my z28 I got hooker 2055 headers and the O2 sensor is located on the drivers side but my question is I ave one in there its just not connected and the wire is literally dangling under my car....its just a a solid single wire...but now my real question is IDK where exactly it goes connected too? like Ive looked in my engine compartment and cant find it..how does it look like?or is there al alternate way to wire it...because Im running my car with out it and im getting bad gas mileage aka 10 MPG in city.

 

and and by the way the engine I have is a LG4

You'll have to figure out where it plugs into the wiring harness.

The length of the wire furnished with the replacement part seems to limit the area where you might look for the place to plug it in.

All that is assuming that ANYTHING under that hood is the parts collection that shipped with the car.

 

dam thats pretty cheap O2 sensor..i might just buy a new one the real pain is gona be finding where it goes into.
