Please Help....... Air / Fuel Ratio Meter Install.

[smok74]

Guys, I've just picked up a A/F ratio gauge (Autometer) and in the process of installing it, I have done everything except connecting the signal wire to the Oxygen sensor.

At the connection for the O2 sensor there are three wires (R33 Skyline), LIGHT BROWN (with white stripe), WHITE & BLUE (with a thin white stripe). Now, my question is, WHICH is the signal wire from the O2 sensor ?

Any help is appreciated.

Dont connect it directly to the O2 sensor, wire it into the harness where it connects to the ECU. Just do a search on this forum or on google for the pin outs to the ECU.

yeah i connected to ecu, can't remember which pin, easier then running a wire into the engine bay

Got it all hooked up. It's pin number 29. patched that straight to the signal wire of the Autometer (purple)
