j/w if anyone had a picture or new what the O2 sensor wire looked like. i read up that it's white and big, but all i found connected to my ecu were small wires. i need i cuz i am trying to hook up my autometer a/f gauge. thanks much in advance.

 

you can wire it anywhere between the harness and the sensor on your primary sensor, and yes its the white wire

btw dont trust a narrowband a/f gauge, its basically a light show (not very accurate at all), but it does kinda look cool....lol
