I want to replace the factory Clarion head unit for the Bose stereo sytem in my 1993 Nissan Maxima. I saw that there is a adapter wire harness called Nissan 84-94 Headunit Replacement Converter by P.I.E.(PIE-HRC-NISS). Is this the solution? I don't want to dump money into my car to gut it and rewire everything nor do I want to buy a new head unit that is bose compatible. Any advise will be appreciated.
