So ive finally decided to install my autometer narrowband afr gauge but was told the 3rd wire(non power/ground wire can be tapped into an existing fuse # anyone know or knows what to tap the purple wire into?
its a 02 svt focus
I tried but ended up having to go right to the O2 sensor coming off the header jsut before the Cat., There are 4 wires but i forget which one it was, a local mechanic told me which wire colour wire it was.
I know there is a way to do it without going to the o2 sensor.
im gonna keep looking. NOTE its not a wideband so this shouldnt be to difficult right?
*EDIT*
Air/Fuel Ratio ââ¬â Oxygen Sensor Gauge Installation
White wire at pin 60 of the PCM or white wire at the computer side of the O2 sensor connector
