Metra Harness Simplicity
2003 Subaru Impreza 2.5 RS
Crutchfield Customer Review (What's this?)
Using this harness was as simple as it gets, all colors in the harness matched the existing car wiring so it was an easy one to one match up to connect it. It worked correctly and as advertised when plugged into the new Stereo.
Pros: Correct color coding Simple connections
