Wideband o2

that is a wideband...the wideband o2 sensor has the same thread as your factory o2 sensor so you can install it in there by removing the factory one temporarily, or you can go to a muffler shop to weld an o2 bung in your exhaust

^^ weld that to the exhaust so u can thread your wideband o2 sensor. The screen/gauge needs DC 12v and ground. If you want to "record" what the wideband is reading, there are two wires in most cases that are used that you plug in to a box or an adapter into your laptop.
Thats all there is to it.. of course assuming you know what the numbers mean... example, 14.7 is stoich for iso octane, and for na applications 12.5 to 13.1 are good WOT afrs...ETC... have fun !
As stated before the PCM doesn't recognize a wide band O2 so the wide band output must be sent to a gauge or a logging device for tuning purposes.
