X740 wire to nowhere

Was under the hood today and noticed this wire harness was not plugged into anything. I can't seem to figure out what it is for. The wires are green and black. Can anyone enlighten me to what it goes to?

I did not receive any voltage reading when I tested it. I tested it while the engine was on, off, and also turned the light switch on and off.

thank you to all

I looked at my X749. It has 3 connectors in that area, but none look like yours. There is one to the air filter/pressure sensor. The other two are not as obvious. You might look at the wiring harness on JDPARTS. It looks like something related to RIO, might be possible.
Mine is a 2011, so later. There are several harnesses and serial number breaks for both models. But, you are correct that the parts list is not particularly helpful in identifying what that might be.
