Hey guys. Today i was installing a rear view camera on my 2012 500 Lounge Air and as i was messing with the wires this white connector fell off. I have no idea where to plug this thing. Do you guys have any clue?

So I'm the owner of a 2017 fiat 500x and am wanting to put my sound system in and have never done it with a newer car. We got the radio out of the dash and got stuck on the back and cannot find an answer anywhere else. I'm trying to figure out which wires go to what if anyone would reply or give...
