On my 2009 CTS-V there is an unused connector. This connector is positioned near the right rear of the engine and comes out of the the wiring harness that supplies the wiring to the three main connectors on the ECM. I noticed it because it was partially "unwrapped" and determnined that it is a six-position connector - two rows of three openings - with a male connector plugged into a female connector. The female half has five wires - orange, pink, black with white tracer, green, and blue with white tracer. The male half has nothing connected to it. I looked for such a connector in the factory service manual and could not find it. The closest thing was the front pedestrian protection connector which the CTS-V does not have (but my wife's 2008 DTS does), but all six wiring positions were used and the wire colors did not match what was specified in the factory service manual.

Anyone know what this connector was intended for, and why was it partially uncovered on my car?
