Hey guys, in finally setting up my A/F ratio gauge in my car. been like two months but im finally getting around to it. real quick tho cause im iring it up, anyone know which oxygen sensor it goes to? and what color wire is the sensor signal wire is? these instructions are FTL. thanx.

signal wire is purple i think...

if youre not using a wideband sensor and gauge, all youre gonna get is a lightshow

It should go to your PRE-CAT oxygen sensor. As others have stated, it's pretty much a light show- it detects feedback mv from 0-1000 (I think) and that's how it figures out if you are lean or rich.

yeah its just something for me to play wiht till i can get a wideband for now, I just hate having it in my car and not hooked up, even if its only going to give me a mini christmas show in my car lol.
