Installing for the first time.
 

I have been doing research on finding people to install a rear view camera and the windshield washer with lights on it but I can't seem to find anyone really.

I have a Kenwood DDX6019 radio system already put in and am trying to connect a Night Vision License Plate Car Rear View Backup Camera and 2xUniversal Black Blazing Windscreen Washer w/ Blue LED. It looks pretty simply for the rear view but the problem is I don't Know where to connect the wire to.
