i am just about done installing my hsw dry nitrous kit and microedge controller and the instructions didnt say which 02 sensor to hook it up to. im pretty sure they are different right?

anyone? thats the only thing left on the install is which o2 to connect that wire to coming off the controller.

Are you sure they aren't referring to an aftermarket wideband O2 sensor??

If you only hook it to one of your primary (upstream, before cat) O2's, you'll only be monitoring one bank of cylinders...which is pretty much useless.

well i just called harris speed works today and the guy told me it doesnt matter which one. the controller is supposed to hook into it to detect a lean or rich condition, it says it will work with narrowband or wideband

In that case just hook it up to either the Bank 1 or Bank 2 primary upstream sensor then.
