I know for sure that there are some adapters. I don't have the CD changer, but the harness is obviously there. I know Blitzsafe and others have adapters, the question really should have been, do these work without the CD changer? Blitzsafe won't tell me. I'm just too cheap to spend the $75 bucks to check it out. I'll post a link at some point to a website where these are available if anyone wants to check it out. Thanks anyways, tough question.
