WE B CRUZN

Hi guys n gals like the title says I have a Clarion DXZ665MP yup I know it's an oldie but it was in the truck when I bought it and untill I can get up the dough for a fancy new one it will have to do. So what I need is an install manual with the wiring diagram so I can figure out so I can figure out what goes where and get me some tunes. So far all I can find online is the Operation Manual.
Thanks
