Air Fuel O2 Sensor Wires for S/C VX S.

[VT_sleeper]

Hi Guys,

I am trying to determine if the wires for the O2 sensor at the ECU/PCM for S/C are the same as the NA ECU/PCM. E.g. I've been searching half the day and can't find a straight answer. This is for a narrowband guage (yes i know a light show.. its to fill in space until aeroforce tech arrives. but anyway..)

D16 violet/black trace signal +, D15 violet signal -.

signal wire for air fuel gauge

Does anyone also have a diagram/picture of where / which loom on the ecu/pcm these are on so its easier to find?

Thanks.

Why dont you just start it, let it warm up, rev it in park at about 3000rpm and probe the suspected wires with a multimeter? You'll see the voltage fluctuate between 1v and 0.

Thanks, that worked.

But I did notice some of the comments various posts have the signal earth and +ve arround the wrong way.

For anyone else searching on a S/C wiring the following is what I used.

D16 Blue - Black Trace signal -ve and D15 Violet signal +ve.
