I used this from another thread and it works. Black and red are basic power and ground. But the green wire or whatever color your sending wire is, you go under the hood, at the little plastic cover to the left of the battery, take off the cover and you will see this below. Tap into the wire shown and viola! It works for my car, good luck!

Do we have a wideband from factory?

the cars ecu is a wideband in the first o2 sensor. im not sure but i know the dash hawk gets plugged into the ecu and reads all that s***...so one of the o2 sensors have to be wideband. the 1st.
MS3 has both. Wide band before the first cat, narrowband between the two cats.
A narrowband gauge tapped in to the factory narrowband sensor is basically useless. The mixture has been changed by the first cat, plus a narrowband display is basically just flashing lights.
You can't tap into a wideband sensor. If you try, it will throw off the readings by the ECU and your car will not be happy. If you want wideband, you need to weld in a bung before the first cat and add another sensor.
Either way?
The two ways I see are welding in a sensor, or using OBDII data like scan-gage or similar device to read out from the stock sensor through the ECU.

or you can just buy a dp and run off the second sensor because the corksport has no cat therefor your not throwing off any readings.

Anyone install a new bung and O2 sensor into their downpipe for the gauge? And if so, did you manage to modify and reinstall your heat shield?
