Which of the t'ree wire do it be, for the o2 ecu signal that is? I've got a greddy air/fuel gauge that needs hooking up, has anyone used one of these? And one more thing before youse starts in on the hatin', is the ca what they consider a "rich burn" engine? I would say yes, seeing how my exhaust tip is soot black, but I've been wrong before. Happy Holidays to the ca crew and you and yours!!! Peace, love, and rich running, turbo spinning i4's!!!!

one is earth, one is 12v the other is signal. A normal ca18det 3 wire o2 sensor they will be white, red and black. signal, 12v, earth.

Disconnect the 02 and switch ignition key to ign position. (Don't crank car).

You can check by finding the 12v wire for the o2 heater.Then find the earth, the remaining one is the signal.
