Title: Poorly documented but good quality and function
Review: I purchased this harness to install aSony MEX-BT3800U In-Dash CD Receiver MP3/WMA/AAC Player with Bluetoothin my 2003 Saturn Ion 2. After about 24 hours of frustration, during which time I snipped out all of the spliced wires because I had greater confidence in my soldering than in the splices, I hazarded that perhaps all three of the red power wires from this harness should be connected to the single red power wire on the radio's harness. Having performed the necessary surgery I found that everything works perfectly. I may have read this tidbit somewhere, but it certainly wasn't clearly marked on the packaging, and I wish I had known it sooner. Still, all's well that ends well, and I'm very happy with the price and performance of this wiring harness.
