I've got a problem with the wiring on my HO2S sensor. I have a 95' Z-28 with a 383 Stroker. Now I know about the Shoebox diagram and everything like that. But, on this O2 sensor, there are 2 wires that are white and 1 wire that is black (ground of course) and one wire that is gray. I am not sure of the 2 white wires if I have them connected correctly or not. It is the passenger side HO2S Sensor. Now, when they say the right hand side, is that the right hand side sitting in the drivers seat or standing in front of the engine. Would really appreciate clarification on this.

Thank You

Sounds like it's a Bosch sensor then... Black is not ground.

White wires = heater (12v and gnd)
Gray wire = Ground
Black Wire = Signal output

 

Good reference:

O.K. I've got the Bosh HO2S Sensor and I've also got the diagram. Now which wire goes to what like for example Black goes to connector A, Gray goes to connector B, etc.. The problem I'm having is the male connector wires got fried and I need to know which wires go to what connector so it will match up with the HO2S Sensor plug. I know now that Black is the signal wire but what part of the connector does it go to, does it go to B or A. Thank you for your help with this.

 

Based on the information already provided to you, it looks like the black goes to B and grey goes to A. The two white heater wires don't matter which goes to C or D.

 

I want to thank all of you for helping me get this done right. Everything is right on track and good to go. Again, thank you.
