Aftermarket backup camera license plate

I just recently bought a camper top for my 2016 double cab tundra 8’ but it has the double swing doors on the back which required me to remove my tailgate. The stock backup camera is in the tailgate handle, so I had to disconnect that as well. I ordered a new backup camera which connects to the license plate, but I’m having difficulty figuring out what wires to splice together. The new camera has a red and black wire for the power, and a thin red black and yellow wire, with a thicker single red wire for the video cable. The tundra wiring harness consists of a blue, black, white, and red wire. Any help would be much appreciated!
