Extra Factory Wires Question - 2005 Silverado w/Bose/Onstar

Upon removal of my factory 6-disk changer I disconnected the antenna, 24 pin harness, and another small 2-pin harness that has just 2 wires running to it. Can anyone tell me what this small 2-pin harness is for? I thought I should ask before installing my aftermarket stereo.

Thanks for any advice on this.

Found out they are for the OnStar system.
