The wire harness I used is prewired for the aswc-1 so I can't imagine it's wired incorrectly. I will trace all the wires and double check. I suppose I could order another unit and return it if it does the same thing. Is that your suggestion? The website says its compatible with my stereo. So it should work. What are other people on this site using to retain factory steering wheel controls with an alpine deck? Not sure what other option there is besides the unit I'm using that's wired for it already.
