What's up guys I have a 97 Civic DX, and I've been having some issues with my after Cat O2 Sensor or if I'm correct the "Secondary O2 Sensor", ever since I bought my car it's been throwing a O2 Malfunction CE Code and took it down to get fixed and the mechanic shop I took it to fixed it but now it's back and I was told just to get a new jumper harness which I did, but I'm running into a issue I got a HX Vtec Harness and noticed that it doesn't have a secondary O2 Sensor... I have no clue what to do because the harness that came with my car has the Secondary O2 coming from the Jumper Harness not within the cab. So I was wondering does anyone know how I can make this harness I got work?? Would wiring my secondary O2 straight to the ECU work?

now where would I buy the wiring?

 

I usually fish around in some junkyards. It's pretty fun actually.

 

it's 108 degrees I'm not trying to go to a junkyard and fry

 

Aww, come on. I'm the pickiest bitch about being in an air conditioned area, so if I could do it in 105 degree heat with 90 percent humidity, anyone could do it.

 

True

 

That's the spirit!

Nah, but for real though, I ain't gunna make you do anything. Typically the O2 sensor comes with whatever wiring it was connected to past the connector. Other than that, junkyard is the only thing I can think of besides the dealer, and they may not have it.
