i have a 96 integra typeR. There is an O2 sensor located on the header side, like most hondas, but theres also another sensor, that looks like an O2 , but slightly smaller, that plugs into the stock cat. I installed a test pipe instead, and i was wondering how can i bypass this "cat. sensor" so i dont get a warning on my cluster saying that its not plugged into the cat. I also noticed poor performance after like 7000rpms with the cat. sensor not plugged in. So my questions are...how do i bypass it? and what is the real function of this sensor...just tellin u that the cat is present, or a temperature sensor?

thanks.

 

Here are pics of the actual sensor and the light i get on my cluster..hope this helps more.

 

nevermind, i figured it out, it just needs to see a ground. So im just goin to ground the wire to the chassis.
