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
