Does anyone know which wires on the ea air / fuel ratio sensors are which? I am assuming one is earth, one power, and one signal. I would check a manual, but dont have one..
black - earth
green/bleu - to the ecu pin 29 (signal)
grey/yellow - to the ignition switch, red/green wire, on position (so power)
this is from the Gregory's wiring diagram. hope it helps. You putting a air/fuel gauge in???
