I bought nice black leather seats from the salvage yard for my 2010 Maxima S. They are also heated seats so I grabbed the buttons and wiring for it also. When installing them, I noticed there is a extra plug under the driver seat for the heated seat control module but not a plug shown in my car for it. Would the extra plug be under the carpet or would i need to replace the interior harness just for the heated seats? Is there a way I could build a wiring harness for it?

 

I believe the wiring harness for the heated seats will be tucked somewhere under the carpet, or maybe even taped to the harness itself. Good luck.

 

Ok, I will take a look. If there wiring so happens not to be under the carpet, is there another solution I could choose from?
