I recently bought a Carbon edition and I installed the fog lights, to my surprise all the wires were there, so my question is, are the CE’s pre-wired for heated mirrors???

 

Your MAZDA dealer would know.

 

That right there is funny!

 

Yeah I tried that and I get we don’t really know, we would have tear into it.

 

I don't know, but I wouldn't be surprised. I added heated mirrors to a Subaru and the wiring was already there. I'm guessing having only one wiring harness is cheaper for the manufacturer.

 

My guess is that they do have the connector behind the glass because both the grand touring and my car have the same part number for the mirror harness, so I’m still gonna pop my mirror glass off and see what’s back there.
