i have a 2013 Prius 5 with advanced tech package and the JBL HDD navigation with factory backup camera. i am trying to add a switch to the car to turn on the backup camera at any time, but i can't seem to find the right information about the harness behind the radio. i did find a page where someone did this with a 2nd gen but the connector on my car has way more wires and I'm not sure which wire i actually need to tap into in order to activate the camera manually. Thanks in advance!
