Are you trying to wire the aftermarket harness to the factory harness, without a wiring kit? If so, it's not color for color. http://www.installdr.com

The factory del Sol memory wire is white with a yellow stripe or white with a blue stripe. The yellow wire coming out of the aftermarket headunit should connect to this.
