Check Engine Light, new headers

I just installed new aftermarket headers on my 97 honda civic dx and there was no place for the sensor. I was wondering how to bypass this problem? I heard I can solder a resister to a wire and it will turn off the check engine light. Does anyone know what that wire is? And what size resister? Or of any other way to make it work?

Thanks for the help.

easy fix..
your car has 2 o2 sensors.. one before the cat (on stock manifold) and one after... The header most likely has an o2 bung in front, and fails to have the second..
Many companies produce an aftermarket "racing" straight cat to install after the header.. which is just bolted on.. it has the second o2 bung..
problem solved.. =)

I had the same proplem but i fix that I made my o2 sensor cables longer and installed it at the othe sensor hole which is located at the bottem proplem solved
