Trying to figure out what is the unused harness in my trunk is for without going through the entire schematics. It's a 3-way black connector that's attached to the body right below the CD/DVD bracket and on my car is capped. It's got pretty sizable wires, one battery feed, one ground and the third no clue.

Any info is appreciated.

 

Never mind. A quick scroll through the schematics and I've identified it...the CD Changer. Dah!
