Does anyone know if my 1999 accord dx is pre wired with the options it just didn't get them so if I could get the button and the lights or sunroof or watever would it just be plugging the things in ? Like my car didn't come with rear speakers but it had the plug ins pre wierd back their so I just added them so does honda use the same wiring for all models untill the last steps where they either get the options or caps? If it is what would I need to get from the junk yard to make it work?
