Hello, I was given an 03 Maxima and am working out a few issues. While I was working today replacing the radiator I noticed a connector that was not on a plug, with nothing nearby I could not find what it was. Some googling revealed nothing so I was hoping that someone may help identify this connector.

upon closer inspection, there is a mount point on the air intake scoop, with nothing mounted there. The wire is just long enough to reach that point, so I suspect it is related. I do note that when removing that scoop to change the radiator it was only the plastic unit itself. No sensors were disconnected during that service.

 

It's most likely an electronic engine mount. There have been problems with them shorting out and causing other problems. A quick and cheap fix is to unplug it.
