So i'm looking at getting a wideband O2 sensor and i'm not sure exactally how they are setup. i found a few kits like this one http://www.injectedperformance.com/ViewProduct.aspx?ID=3066&VID=42 but they dont really say how they are wired up. i have an a/f guage already and would like to use it. What is everyone else using and is that kit all that i need ?? any info owuld be appreciated, i'm a noob when it comes to widebands and tuning.
