Does anyone know where i can find the reverse wire on a 2000 Maxima to hook up avn 5435 dvd/navigation?

You should download the service manual from Nissanhelp.com: http://x.nissanhelp.com/forums/Knowledgebase.html?catid=20

Go to 12volt .com all the wiring info can be found there. Hope this helps in some way.
