Need Help Badly!!

Hey guys so I installed an aftermarket screen on my sync 1, (looks amazing btw, works fantastic too), thing is, I want to use my factory reverse camera but the radio comes with input with an RCA cable, only thing that wasn’t inputted was this harness into the radio so I’m guessing this is the reverse camera harness, does anyone know where I could find some sort of adapter to plug this into an rca cable
