Hi everyone, I just bought universal 4 wire (bosh) oxygen sensors (no connector) and I need advise with connecting it. the colors and meanings are: black-oe signal; white-oe heater; white-oe heater; gray-oe ground. anyone could explain me how should i mach the colors ? thaks in advance

 

what car?

 

Jag. xj8 1998 4.0l...

 

The OEM sensor's wiring coming from the sensor (the wires from the sensor to the connector). This is if you cut the connectors off of the existing OEM sensor and want to splice it onto the new sensor:

Blue: signal
White: signal ground
Black: heater
Black: heater

Heater signals are not polarity sensitive - you can hook in either direction.


If you are interested in the color codes from the connectors to the ECM:

from the bank A connector to ECM (HO2S A):

Red: signal
Braid: signal ground
Purple/Blue: heater
White/Purple: heater


from the bank B connector to ECM (HO2S B):

Green: signal
Braid: signal ground
Purple/Slate: heater
White/Purple: heater
